Nine Volt Nirvana Tape Measure Boost

I came across some a bunch of schematics for Nine Volt Nirvana, Joe Gagan's old company. While I haven't found any videos for all of them to get an idea of the tone I can guarantee that if Joe Gagan designed it it's gonna sound awesome.

First up, the Tape Measure Boost. The schematic calls for a trimmer for the volume, I believe the idea is to have it as a set boost inside another pedal or stand alone unit, but I thought it would be nice to have one with a volume pot instead. You can also sub the 2N2222 with any other common NPN Si transistor (2N5088, BC108, 2N3904, etc.)

  1. Thanks Zach, that could be a nice sub for the lpb1 which i don't really like. It would be worth addind a filter cap as there is ome space for it on the layout

    1. Just finished up the trimmer version. I'd definitely put this one in the LPB1 territory. Decent amount of boost, but it breaks up pretty easily once you pull it up past unity gain(even when using single coil pickups).

    2. Just 2n2222 and 2n5088 so far. I'll probably try out a few more varieties when I get a chance.
