Rocket Sock-It !

[u1061810]

Hi all,
I just finished my first project using perfboard the Rocket fuzz at GGG
and WOW!, this is a nice sounding fuzz.The pinch harmonics really jump off this thing. Be forewarned this pedal is extremely loud and could shatter your cochlea.
One finding on it though the trimmer is only operational for about 3/4 of it's rotation(CW), then there's a dead spot on the rest of the turn.Just curious if anyone else had this experience with it.

Congrats on your build! You could tack a volume pot on the end though to quieten it down a bit though just my 2 cents

The Rocket is a great Fuzz Tone.
 The Trims set bias on the transistors, twist the one above Q3 while you measure voltage from ground to collector on Q3....set the trim for 1/2v on Q3.
 If you're battery is at 9v, set Q3 collector for between 4.5V and 5V.
 If the trimpot 'didn't turn off the transistor with misbiasing...N/M.
 No, I think you've got it wired right! ! !

You might want to bias it by ear.  You might learn something.  Things that get repeated enought take on a life of there own.

Play a root and a fifth and turn the pot for the sweet spot.  Take your voltage readings after.  Remember it is not a Ge FF

Gus, I built 2 exact circuit's, the first I biased with the dvm, the next one I tried your version, and you know somethin, I think the one that I biased by ear has the best dynamic's.
Good :idea:

Pete, 1/2 supply voltage is a starting point to get a circuit working. Use your ears to fine tune, it will open your eyes to biasing, especially with fets.
  Some sound better at 5.5V, froma 9V supply. What sounds iffy to you might sound good to me, etc.
