hey guys im having the same problem but im not as crafty as u all are so maybe u all can help me out... im pretty sure everything is wired correctly on the bsiab II but no sound when turned on... the led doesnt turn on either... another problem is that the battery gets unusally hot but i moved some wires around on the input and the hot battery problem stopped.. and the pedal made a fluttering sound... well after screwing with the wires on the jacks im back at square one with the pedal not working when its on... i see that u all are able to take voltage readings with a mutimeter and i wanted to know how you all do that... i have a multimeter and ive been unable to get any other readings other than 8.** which i guess is just the battery... how do i get any readings from the transistors... any help would be appreciated to fix this pedal... this is my first build and its on a PCB which i made myself ... well thanx in advance!!!

oh ya one more thing... how can i find the input capacitor or an output capacitor.... would it just be the first or last cap in the circuit?? im talking in regards of  a BAJA TECH Da Moaf fuzz pedal...

with the multimeter, put one connector on the input jack ground and the other to each of the leads of each transistor.  Seems like you need to put a 1/4 plug in the input jack as well if using a bettery.  Make sure you write down the transistor voltages according to the orientation of each transistor (like the GGG example)

Double check that all of your + and - are in the right direction.  Also just use a battery bypass the adapter jack if you are using one.  Your transistor readings are very important.  Set your meter to the correct position like if you were to check your battery (20v) and put the black ground lead on the neg of the board and then probe the legs of your transistor and record the readings.  Post what you have and I bet someone will be able to tell you.  The smartest people are on this forum.  Everytime I come over here I am just amazed!  Good luck! ;D
