problem with bazz fuzz

[copachino]

hi, i have a porblem with a bazz fuss, its version i have already build and verified, but im building one for a friend, the main problem, its that i have build two of them and they have the same problem, even if i got the normal voltages, on th circuit, i only get clean, volumen pot, work but i only get clean and if i hit hard the string, sound a bit distor, but im not so sure where its the problem i have verified that board and have done a coplu of times, but this its the first time that happens this, may be a ground issues??

check your diode orientation, is the cathode facing the right direction in the circuit?

Also make sure that you're using something like a 1n4148 or a 1n914, pretty common diodes. Do you have a picture of your build?

Also, check the pinout of your transistor, if it's flipped then that might be part of your problem too

i have check everything but i will upload some guts tonight
