Tweaking the tone of inexpensive stomp boxes is an obsession of mine. I started modding mainly because I refused to spend $200 to $300 or more to achieve great tone.

Most boutique pedals are clones of other inexpensive pedals anyway with the main difference being higher quality components. By upgrading the signal path and changing a few component values here and there, cheap inexpensive pedals can be drastically improved.

Take for example the Boss DS-1. You can buy them new for $40. I've personally bought used DS-1s off eBay for $25. Add one of my mod kits and for well under $100 and a little soldering time you've got a pedal that will rival pedals costing five times as much.

Add to that the fact that YOU personally took a very bad sounding pedal and made it usable. There's a certain level of self-satisfaction that I get knowing that I added a personal touch to a piece of gear that I use.

Take my new Chip Adapter Mods. You will not find these types of mods available from any other modder. This is a major breakthrough for DIY. The opamp is where the tone takes shape. Upgrading the toneless inline chips with a more Hi-Fi Dual Opamp such as the Burr Brown
OPA2134PA will transform the tone of my already popular mods into even better mods. Add to that the ability to swap out different opamps and you've got a very effective tone-shaping tool.

8-8-2010New CS-3 Ultra MP3 Now Available - I have recoreded an mp3 of my New CS-3 Ultra Plus Mod. You can listen to it here.

7-9-2010Guitar Treble Bleed Switch Mod Now Available - This is a very cool mod for your guitar volume pot that will give you a variety of tonal options. You can find it here. I have always liked the Treble Bleed Mod but there were certain times when I missed the mellower tones that rolling back the guitar Volume would give me. So I developed this mod that will actually gives me three different options. The switch allows you to switch to (1) cap/resistor, (2-middle) stock tone, (3) cap only.

The Cap/Resistor will allow you to retain the highs as you dial down the volume pot.
The Middle position bypasses everything and gives you the stock guitar tones. And the other side of the switch with just a cap will retain the highs as you dial the volume pot down but will also affect the bass and mids. All three, when used in conjunction with the guitars tone pot(s), will give you a wide Variety of tonal options. Monte Allums


7-4-2010 — I have just released a new mod for the CS-3. It's called the CS-3 Ultra Mod and you can read about it here. My Boss CS-3 Opto Mod has changed very little since its introduction. The Opto Plus is my best selling Mod I currently sell. It is the first effect in my studio and live rigs and it is always on. So, you ask, why change it? Well, many have asked me to create specific mods for the CS-3 and I already had some ideas of how to improve an already great mod. The result is my New Boss CS-3 Ultra Plus Mod. Here is a list of the specific improvements this Mod offers.

Attack – I’ve been asked if I could smooth out the attack of the effect. With the Ultra Plus Mod I have accomplished this by smoothing out the attack and giving it a more natural feel.

Warmth – With my original Opto Mod it was my intention to preserve all the original signals frequency content while lessening noise. I have maintained all those improvements but I have added a bit of warmth and thickness to the affect. With the Ultra Plus, Warmth and Thickness increase as you dial up the Sustain Pot. This is a very cool feature of the Ultra Plus Mod.

Sparkle – Most inexpensive compressors shave a bit of the high end from the signal leaving the effect sounding a bit dull and lifeless. With the Ultra Plus Mod I wanted to add a bit of high end Sparkle to the effect. The harshness of the stock CS-3 has been eliminated and a very smooth high end Sparkle has been added to the affect.

Harmonic Content – I am a Pinched Harmonic Addict! Take a listen to
Roy Buchanan on the 1962 recording of "Potato Peeler". Another guitarist that frequently uses pinched harmonics is Eric Johnson. The effect happens when subtle harmonics are amplified. Pinched Harmonics require that fundamental frequency content be preserved. The timbre of Pinched Harmonics is greatly affected by a guitarist’s ability to maintain fundamental frequency content in their signal path. The Ultra Plus enhances the fundamental frequency content from your instrument and thus making Pinched Harmonics more musically pleasing.

PDF Instructions – I have created the CS-3 Ultra Plus Mod instructions in the popular Adobe PDF format that can be easily printed from your computer. The instructions are crystal clear and full of high-resolution pictures that clearly illustrate how to perform the mod. The PDF instructions are e-mailed to you once your order has shipped. All orders ship within 24 hours of order placement! We Ship to anywhere in the World! - Monte Allums

5-2-2010 — I am putting the finishing touches on a new pedal design. It will be called "Versa Drive". It will be a boost pedal and low gain pedal that will mainly be used as a boost to push an overdriven amp over the edge tonewise. But it can also be used as a light OD pedal for those looking for a little edge to their tone. It will be a very versatile, hence the name "Versa", pedal. I am very excited about it. The best part is it will be a very simple build. Please help me spread the news. This will be an exciting addition to my pedal line.. Monte Allums

1-28-2010 — I have 7 used BD-2 pedals that have been modded with my New Blues Stack Mod available here. They will be sold on a first come first serve basis. I've gotten a ton of requests for them so I know they won't last long. The Blues Stack is the best BD-2 mod I sell. It's super smooth and FAT with a very organic natural overdrive. You can use it as a boost, OD or as a flat out distortion. And the nasty decay is GONE! Monte Allums

1-10-2010 — I have created a very cool mod for my OD-308. For those of you that are lucky enough to own one you can download the mod free by clicking here.
It's called the OD-308 Vintage Mod. It get the tone of the OD-308 closer to that of the famous Vintage RAT2. Monte Allums

1-9-2010 — I have 10 Fully Assembled OD-308s for sale here. (Update 1-14-2009, only 3 left) I will sell them on a first come basis. These will sport a Black Label instead of the Silver Label that is included in the OD-308 Kits. These OD-308s were assembled by me personally and are signed for authentication. Monte Allums

12-4-2009 — Just read a negative review on HC. Guy gave me a 1 for customer service. Said it took an eternity to get his order. Let me make one thing very clear, I ship ALL orders within 24 hours of the initial Paypal notice. The only exceptions are if it's a Holiday or I have closed the site for sickness and vacation. If you need your order fast then choose Priority Mail. I have no control over how long it takes the postal service to deliver a shipment once it leaves my studio. Monte ALlums

12-2-2009SSS Copper Strat Shields are now in stock. The way these are selling, if you've been holding off ordering one I suggest you order now. They are going fast! Monte ALlums

11-30-2009 — I have a slightly bent Tele Shield that was returned. There is nothing wrong with it and will work fine once installed. If you are interested send $10.00 to tvon@monteallums.com. First $10 gets it shipped. Monte ALlums

11-2-2009 — The new RAT 2 and You Dirty RAT Mods are ready and shipping. See them here. Monte Allums

10-14-2009 — The OS-2 mod is ready and shipping. See it here. This is a super FAT Distortion/Overdrive that will knock your socks off. Again, the Dual Fairchild NE5532s sound FAT and smooth. The NE5532s have a certain magic that is undeniable in this circuit. If you own an OS-2 or even if you do not, buy one for cheap and mod it using this kit, you can thank me later. Monte Allums

10-9-2009 — I have a guitar and a few modded pedals for sale here. These were some of my pedals that I used to create mods and I have just got too many so I am selling a few. The guitars are from my personal stock. Very personalized and are great players. I just have way too many guitars and pedals. No place to put them. The other day it took me 15 minutes to find a particular guitar. Pretty good indication it's time to let a few go. These are great players and you will not be disappointed.

Wow, just got through playing the Kramer I have for sale making sure the setup is perfect and ready for shipping. Man, someone better buy this guitar before I change my mind about selling it. This guitar is going to make someone very happy. I'm telling you this guitar plays and sounds better than guitars costing 5X as much. I still may decide against selling it. Someone better buy it before I change my mind about selling this gem! Monte Allums

9-19-2009 — New videos of my New BD-2 Blues Stack and DS-1 Roxx Tri-Gain Plus Mods are up. Click here for the Blues Stack and here for the Roxx Tri-Gain Videos.

8-20-2009
This is my newest mod for the DS-1. I'm calling it the "Roxx Tri-Gain Plus" mod because simply "It Rocks"! This is the name that came to mind right after I finished the mod.

This mod is built around a pair of NE5532 opamps. It’s pretty amazing how the NE5532s sound in this mod. All the harsh spiky highs have been removed. The stock DS-1 has a very fake sounding distortion. Not very natural sounding at all. In my opinion this is where most pedals fall short.

I will not be offering a cross-grade or upgrade for the Roxx mod because the Roxx is a complete mod rebuild. It is totally different from my Rectifier mods. This, IMO, is my best DS-1 mod to date. I built it around dual stacked NE5532s. This completely removes the fizz from the DS-1 circuit and gives the pedal a very natural sounding distortion. In fact I almost named the mod Velvet because this mod has an almost velvet type smoothness to it. Check it out by clicking here. Monte Allums

All mod instructions include the buyers name and Paypal transaction number encrypted into the instructions that I send after the purchase. I am doing this to try and stop people from sharing and pirating my work. Since the name and transaction number are encrypted, with special software, you will not be able to simply search the code and find it. I hate to have to resort to this, but at least this way if my instructions show up on the net I’ll know exactly where they came from. And don’t fool yourself, I will litigate if I find anyone sharing my hard work. This is how I feed my family. So please don’t share my hard work with others. If you do, and I catch you, you’ll be out more than the cost of the mod. Monte Allums

7-30-2009 — Chad Matthews, who does all our mod installations for the USA and Canada, is taking a few weeks off from modding so I'd like to introduce everyone to Merv Jones. click here for Merv's e-mail contact info. Merv is located in Spokane Washington. Please contact Merv directly if you are interested in having your pedal modded. Merv is authorized to install all of the mods I sell so you are in good hands. Welcome Merv! Monte Allums

7-28-2009 — I am extremely excited about a new BD-2 mod, It's called the BD-2 Blues Stack Plus Mod. If you'd like to check it out click here.
This mod is different from my H2O mod in that I have built the mod around the Dual Stacked NE5532s. Taking nothing away from the H2O, the H2O is a top selling mod for us. I just felt that because of the very unique tonal qualities of the Dual Stacked NE5532s that it would be great to build a mod around them. The stacked NE5532s is the only mod offered by anyone that finally solves the nasty splaty gain decay issue that plagues a stock BD-2. I have also eliminated the fuzz-type gain the BD-2 gives you when the gain knob is dialed up. And I am the only modder that sells the Dual Stack Adapter this mod uses. The Dual Stack Adapter was a design I came up with and is made exclusively for me. You cannot buy this adapter anywhere except at my website.

The BD-2 Blues Stack Plus Mod is designed with Blues, Gospel, New Country and Classic Rock players in mind. If you're looking for Hendrix, SRV, Rascal Flats, Led Zeppelin or any of the Classic Rock and Blues tones, you need look no further. The Blues Stack Plus delivers those tones to you and it does it with one of the warmest, most musical, natural sounding Overdrives you've ever heard. The gain is warm and natural with excellent pinched harmonics and excellent note clarity. Dynamics are just as good as the H2O mod, as is transparency. You can also use the Blue Stack Plus in front of an already overdriven amp to push it over the edge into sweet saturated bliss or in front of a clean channel amp for warm overdriven tones. This is a very versatile pedal after the mod.

7-22-2009 — I am putting the final touches on my second pedal kit design. We've been working on the design for about 8 months. It is a boost type design. It is meant to be placed in front of an already over-driven amp and will also work in front of any overdrive or distortion pedal. It will have three modes — FAT, Vintage and Fine Boost modes. It's a very unique design that will add a Fattening Effect and Sparkle to your signal. I expect to be shipping the pedal kit within the next few weeks. Monte Allums

7-1-2009 — For the entire month of July those that buy 3 mods of at least a $19.99 value will get a 4th mod free. Just add a note with your payment or drop me an e-mail letting me know which mod you'd like. Monte Allums

6-12-2009 — Well, you asked for it and now it's available. I have received several requests for an adapter that you can use in a Tube Screamer, SD-1, RAT, etc. to stack opamps. I've even used it to stack two LM308Ns in my new OD-308. Results will vary depending on the circuit but I've gotten some very interesting results using this new adapter. You can order it here. Enjoy! Monte Allums

6-11-2009 — I am being forced to increase what I charge for shipping International Orders. So as of today I am increasing my regular International post rates from $3.50 to $4.50. USA rates will stay the same. Monte Allums

4-15-2009 — The OD-308 Version 2 is now shipping. Version 1 buyers may upgrade by going here. The OD-308 Version 2 now has a buffer incorporated into the circuit. A great pedal just got better! Monte Allums

2-15-2009 — Well, it was bound to happen. I just got ripped off ($170.84) by a buyer that paid by bank draft. In the past I have never held an order until it cleared Paypal. But, all it takes is for one crook to spoil it for everyone. So, from this day forward, if you pay with an eCheck or Bank Draft I will not ship your order until the funds clear Paypal. I have created a page publishing the name, address and e-mail of these ripp-offs. You can access the page by clicking on the "Stolen from Me" button above or by clicking here. Monte Allums

1-25-2009 — I am currently working on my second DIY full pedal kit design. This pedal kit, unlike the OD-308, will be very much like a Treble Boost. It will work best with an already overdriven amp. But I am designing it where it can also be used in front of a clean amp setting. So this will be a very versatile DIY Pedal Kit. The best part of this design will be it's simplicity. Not a lot of parts so it will be a very simple build. Monte Allums

12-20-2008 — I am extremely excited about a new mod. You can check it out by clicking here. This "Dual Stacker" chip adapter is now included with several of my Plus Mods. I am sitting here in the studio playing an H2O modded BD-2 with the new "Dual Stacker" adapter. If you are familiar with the BD-2 then you know about the nasty unnatural decay that you hear on the trails of a note. I have solved this issue with my new mod. If you have recently purchased one of my new Plus mods and would like to upgrade to the new "Dual Stacker" mods I have created a webpage that will allow you to do so. Click here to access the upgrade page. Monte Allums

OD-308 DIY Kit The OD-308 is getting rave reviews! They feel, as I do, that the OD-308 may be one of the best OD pedals ever designed. There are pedals that sell for 3Xs it's price that are not as good. I've played some of the best OD pedals available and the OD-308, IMO, beats them all hands down! If you want one of the most dynamic, warm, rich and smooth OD pedals designed today then the OD-308 is the pedal you've been looking for.

I think some are intimidated by pedal kits. Actually, they are easier to do than a pedal mod because there are no components to remove. With the OD-308 kit you are just populating a PCB and soldering wires. So it's actually easier to do than a pedal mod. And you don't need to know how to read a schematic. I include very detailed pictures and diagrams that makes assembling the OD-308 extremely easy. So if you have been holding off because you felt a pedal kit would be too difficult let me assure you it is actually very easy to do with the easy to follow instructions I include. Monte Allums

10-14-2008 I have decided to stop selling my products on eBay. eBay fees have soared out of control and with profits being down I just cannot justify their high fees at this time.

9-18-2008 OD-308 DIY Kits are Now Shipping! I've already sold a good part of the first 250 so if you want one of the first 250 get your order in now. Once the word gets out I have a feeling this is going to be a very hot item. Monte Allums

7-18-2008 They're here! Both .006" Strat and Tele Copper Pickguard Shields and the .018" Aluminum Strat Pickguard Shields are both now shipping! These are now the Thickest, Best Quality Pickguard Shields sold anywhere. Click here to go to the web page. Monte Allums

7-4-2008 I have completely revamped my Pickguard Shield line. We will no longer cut these by hand. All the Pickguards I now sell are Precision Laser Cut. These are Ultra-High Quality Shields. We now offer the thickest Copper and Aluminum Pickguard Shields on the Net! But, I didn't stop there. I have tweaked the designs so the Shields will fit 95% of the Pickguards in the market without modification. I will no longer sell the adhesive-backed pickguard shields but I will continue to sell the 1.25 mil 12" x 12" Adhesive-Backed Copper Sheets and the 40-gauge 12" x 12" Copper Sheets. Available now! Monte Allums

6-11-2008 Many Thanx to Sean Borton for allowing me use clips from his new album "What a Party". Do yourself a favor and visit the mods page and take a listen to Sean. Sean has fabulous tone and is one heck of a player. Monte Allums

3-22-2008 - World Renown Producer and Engineer David Prater, who has worked with bands such as Dream Theater and Firehouse, contacted me a couple of months back. He was interested in my New CS-3 Opto Plus mod for his two CS-3s. According to David the CS-3 has been one of his secret weapons for several years. That's right, David Prater, who could use any piece of gear he wants, sometimes uses Boss CS-3s to record vocal tracks. David told me he loved the spongy vibe they give him but wanted to quieten the beasts down a bit. So he sent his CS-3s to Chad Matthews and Chad did my new Opto Plus mod to them, that incorporate my new chip adapter and a Burr Brown Chip. Well, David loved the Opto Plus Modded CS-3s and is using them on his current recording project. And to top it all off David recorded an mp3 with one of his newly modded CS-3s.
