build yourself one.

one fuzz to rule them all? naaaaaaw.... but a little bit closer

lardacious is the tone control, it uses a curious feedback arangement that is not as lossy as standard tone controls. it combines adjustable feedback with a faked variable cap to achieve a wide range tone control with minimal loss.

[b]phat[/b] pumps up the low midrange. to the left of the dial, its a treble booster, to the right more mids and lows as you turn it up

monkey is a combo bias/starve control for the second transistor. it lets you dial in everything from very blatty broken gated fuzz to a very smooth overdriven octave up fuzz when pegged. the more ya monkey with it, the more sounds you can find.

balls makes you deaf, so turn the motherfucker down!!! seriously, this thing is unity gain around 12:00.

a whole lotta tone for two transistors.

q1 should be ge. i purposely did NOT measure it before i put it in. i wanted to do a circuit where anything would work as long as it was ge and npn. so socket and tinker.

q2 should be silicon. i spec mpsa06 cuz i currently have a love affair with them, but any qs around 200 should be fine. if ya need to use say something with an hfE of 400-500 or so, add in a 47-100 ohm resistor between emitter and ground. that will help get the gain where ya want it without fucking up the tone too much.

this thing will sustain literally forever. the video, too long for sure, just touches on all the crud ya can do with it.

when i get around to making a vero, will post. i think i can stick a fork in ths one. try it on your breadboard i think you will be very pleasantly surprised.

peace out

PjP

ps: c11 got cut off a litle and is 33 picofarad

i made a slight mistake on the schematic, i messed up one node a little. attached is the corrected and verified schematic, and a vero layout. i haven't built this one yet, but unless my jaded old eyes decieve me, it should match the schematic.

sorry for the mistake, hope it didn't f anybody up

far easier to read schematic thanks to sominka on aron's

i DO have boards in if you want one.

i got no work this summer... last years, 4,5, even 6 gigs a week. now nothing. so i'm asking 20 bux shipped (in the usa, 20 plus shipping to other countries, sorry, i am broke as fuck) per board, and will include the proper transistor (mpsa06) with them and a schematic/layout. it will just fit in a 1590b, a 125 would be easier.

pm me if interested ;)
