DS-1 Roxx Tri-Gain Plus Mod


MPORTANT – This mod will only work with the newer DS-1s. The older vintage DS-1s use a different type of inline chip that is not compatible with the chip adapter. Your DS-1’s PCB must look exactly like this.

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.

Getting a pedal to sound like an actual tube driven amp on the verge of breakup is the challenge pedal manufacturers face. I have been able to obtain that vibe with this mod. All the fake shrill gain has been replaced with a very smooth dynamic harmonically rich distortion. This is arguably my best DS-1 mod to date.

With this Kit you will receive a 3mm Super Bright Clear White LED, Solder and Desoldering Braid along with detailed easy-to-follow High Rez PDF Mod Instructions sent to you as an e-mail attachment.

IMPORTANT – Boss has started using surface-mount components on some of their new pedals. I’ve created a page to help you determine if your pedal is moddable. Read about it here.
