Hi, just built a Fatpants. First, let me say this was my first Madbeans board and it was a pleasure to work with. Logical layout and GREAT Documentation! I'll be using more of them in the future.

Back to the issue. Here's what I'm getting:
Clean bypass signal
LED lights up
With pedal engaged with Volume maxed a little less than unity
NO change when adjusting the Bias Knob What I've checked:
All Grounds confirmed
Continuity on all other parts of the circuit
Getting 17v at the extra pad as well as the trim pot
All resistors confirmed before install and after
Diodes confirmed- ok
All capacitors are 25v or higher
I used the gaussmarkov wiring and it's confirmed (I like it for it's simplicity. Leads will be trimmed when I have a working build.)
Parts values confirmed (Multiple times)
Traces intact and no solder bridges- overall fairly clean Both Pots confirmed for range and value
So, don't know where to go next. I suspect the J201. Are these sometimes defective?
I don't know how to verify the film cap values other than from my order.
Any thoughts or ideas appreciated. Thanks!
