Hi there,
This is my second bluelay build, first one is working like a charm
The build phase went seamlessly, no bad soldering, no component looking bad, I checked a dozen times
V+, Vcc and Vb are ok
But, when plugging in, the pedal is saturating, could be a hm-2, even with very low feedback
Following signal path :
- IC1 pin 1 : signal clean
- IC2 pin 16 : nothing
- IC2 pin 15 : little saturation, can hear effect
- IC2 pin 14 : signal saturated, can hear effect
- IC2 pin 13 : nothing
- IC2 pin 12 : signal saturated, muddy, can barely hear effect
- IC2 pin 11 : nothing
- IC2 pin 10 : signal saturated, muddy, can barely hear effect
- IC2 pin 9 : signal saturated, muddy, can barely hear effect
- IC1 pin 7 : signal saturated, muddy, can barely hear effect
Attached zip contains an audio file where you will be able to hear what it sounds like, taken with a probe on signal points above, with respect to ground
I really don't understand what causes this saturation on IC2 stage...
