welcome to Apocalypse Audio, your haven for DIY guitar effects in the end times. so, start prayin to the fuzz gods, savin up those parts, and remember, when the big one goes off- keep your transistors shielded from those pesky electromagnetic pulses!

H-FUZZ

here's a pedal i built up for a buddy of mine the other day.  he plays bass in the local chicago trio Hobo and Boxcar, and wanted something that he could use for bass as well as guitar.  i built him up a circuit that i came up with based on the Fuzz Face/Wooly Mammoth model, that shines when it comes to double duty fuzz action.  it's basically a tweaked fuzz face with russian GT309 transistors (a new fave of mine), that has the fuzz factory/wooly mammoth adjustable NFB gate control, an input gain pot, a max gain trimmer, and a LPF/switchable HPF adjustable tone control, similar to the Big Muff, that allows for guitar or bass functions.  the mid shift switch allows anything from fat scooped bass, a dirty overdrive, or mid-heavy motorhead style grind.   for guitar, it's capable of anything from monster thick doom tones to mosquito sixties style fuzz. topped off with some sweet vintage knobs, it's a great switch-hitter.



as an aside, after taking this picture, i realized that i wired the center pots up a little tight, so i simply switched the two middle pots around. now, if the nuts loosen up, the wires on the pots won't get pulled out so easily. a word to the wise- leave enough slack on your pots!

    What about a vero board layout?

    thanks,

  2. if i have a chance, i'll do one, but i'm working on some other projects at the moment. it's basically a wooly mammoth, so you could adapt a WM vero easily.

    any possibility of getting a shot of the other side of your circuit board? I'm having a hard time translating the schematic to a board. any pointers?

    What I don't see in the schematic is the footswitch, where might that be?

    thanks,

  5. sorry, this box is no longer in my possession. footswitches are generally left off most stompbox schematics, as true bypass pedals are generally the same throughout. i suggest looking at some of the links on the page to the right. Geofex has a lot of good info, and general guitar gadgets has wiring diagrams of every type of bypass you could ever want. as far as the vero layout, i don't have one drawn up at the moment, possibly some time in the future. i'll try and make it sooner than later.
