I just built a tremolo pedal from Musikding "optical Tremolo kit".
I had already mounted a fuzz-face without problem some time ago.
But there is a problem with my tremolo pedal!
The pedal works when the effect is not activated (bypass)
The LED is on and reacts when I change the speed of the tremolo.
I did "open" the small internal potentiometer (trimmer) ... nothing.
I have a doubt about 2 components supplied which do not correspond to the listing:
At location A0I1 the component VTL5C2 is replaced by the component NSL-32
At location IC2 the component RC4558 is replaced by the component with UTC SKTL reference (if I read correctly)
Is that it (Musikding would have made a mistake?) Or did I mount a component upside down? ...
I checked the direction of the capacitors, it looks OK ...
In your opinion ?
