So I just built my 1st BYOC Tremolo pedal. It is not the first time I have ever done this type of work either. Have lots of experience with SMT boards and assembly/soldering.
The Tremolo pedal works in bypass, the LED works, the Level control works. The Rate is very flaky. Not even sure the Depth has any function at present.
What happens when turned on is the following. The LED lights up and at anywhere from 1:00 to minimum, the rate does nothing and the LED is solid. If I turn the rate to maximum (about 5:00), it flashes but the effect is fairly minimal and as I decrease rate, the LED starts to slow down but at about 1:00, the LED remains solid.
I took some measured voltages based on what I read in another thread. This is what I found:
Q1:
9.5 V
7.6 V
4.5 V
Q2:
1.01 V
1.61 V
5.36 V
Q3:
0 V
~12 mV
0 V
Q4:
0.0 V
0.6 V
3.4 V
Attached are some pics. I have also read in another tremolo thread that there were some bad transistors out there. Is that a possibilty with mine?
