Hi, how are you?.
I need your help! 8) 8) 8) 8)
I built the Muffintop, the problem I have is that it does not sound.
I used the Audio Prove and I noticed that the sound arrives until G of Q1 ( blue line in the photo) :

*the red dots are points that touch the audio prove and did not sound
I have taken all voltages of the transistors, are:
( power supply voltage: 8.99 )
Q1:
D:8.99
G:0.09
S:0.00
Q2
D:8.99
G:0.09
S:0.00
Q3
D:8.99
G:0.09
S:0.00
I reviewed 3 times all components and everything is in order.
the only thing different that I'm taking are the 2N7000 instead of BS170, obviously 180 ° turn around
please help I do not know where to start and what to do first.
thank you very much
Francisco

someone? please :)
I tried with a few 2N5457 and nothing :-[
I don't really have any great advice.
It looks fine in the picture, but did you check to make sure there aren't any solder bridges from the signal path to the ground? If there is then your signal is getting grounded out.
thanks for helping
I checked the pedal and I have no solder bridge or anything like that.
I really did not know what to do
It's hard to tell, but do you have 2 lugs grounded to 2 separate grounds on the pcb?

I put all the ground's in the slave is the only difference with the photo
I made that connexion to test the effect without the 3pdt
