Hi,

I build the same layout shared above. It sound very dull.
Do we already have any verified build reported?

I just made it but doesn´t work well. The output control doesn´t elevate so much the volume in comparison to the original (I have one), the ratio control in its maximun position mutes all sound and the other two controls doesn´t seems to do anything.
I used 2N5088 instead MPSA18 and BF245B instead of 2N5484.

Anyone else made it work?

I assembled the layout, the pedal worked well, some jambs were not noticed. But it works only with 5484, the other tests gave distortions. How to collect Diamond, I'll choose what to define in the case)

I have traced the original pedal... It has been already said that it's a BYOC 5 knob compressor with some minor adjustments.

There you have it all... it's a verified project, start tracing a PCB.

maybe the problem lies in the field effect transistor
Try to set a tri-peak between current and drain
P.S.
Are you sure that the ba6110 and lm13700 are interchangeable?

IC 1 - what is it?
Looks like a p-channel mosfet, for reverse polarity protection.
But i can`t see the markings.

It's very strange component placement, but IC1 is a 5V power regulator for U3 MCU (IC1 has 71F(4?) L0EB marking on the bottom which identifies it as LM2940)
U1 seems like a p-channel mosfet though

I agree.
Nearby stands u1 looks like 78l05, strange.

Hello, I know it was a long time ago that you commented on this, but did you find the problem? I'm having exactly the same problems as you said. I've tried everything and still have the same problems.
