The stock Big Muff Pi New York City Version has potential but that’s about all it has. It just falls apart in a mix or live band setting. There’s just no meat with those potatoes. With this mod I have done two things. I first flattened out the EQ, added mids and sweetened the highs and brought the bass and mids back in focus. Second I have evened out the gain and added much needed focus and harmonic saturation. But that loose Hendrix type fuzz vibe has been enhanced and tightened. This is the closest I have ever gotten to those “Foxy Lady” and “Purple Haze” tones. That’s the only reason I bought this pedal. I knew it had a great foundation for that tone. In all honesty I’ve had this pedal for a few years and have attempted to finalize a mod for it during that time.
This was a hard nut to crack! But my persistence did pay off and I’ve had a blast duplicating those early Hendrix tones with my modded BMP. In my research I found that many of the BMPs use basically the same layout with different values, so if you can read a schematic you can adapt this mod to many of those versions. When time permits I will eventually create mods for a few of them. So please do not phone or e-mail me about them. I will work on them when I get a chance. Right now I am busy expanding my product line with more products and there are only so many hours in a day. So please be patient. The mod also includes a Boss-style power Jack to replace the stock power jack. I also include a very cool 5mm Super Bright Blue LED to replace the red stock LED.
IMPORTANT — Make sure your pcb looks like this.
BMP_NYC.mp3 — Played through a Strat into a modded BMP into a Black Faced Super Reverb. Mic’d with a SM57. Delay added in Cubase. Just a rendition of Purple Haze and Foxy Lady sorta blended together to show the classic tones this mod can achieve. If you’re looking for the old classic Rock tones then you’ll be extremely happy with this mod!
