I switched out the jfets…wired up smd’s with legs and still nothing. Might just get a new board and start over.

@jwin615 you might have a good point about there being some sort of solder bridge on the actual jfet. I'll see if I can clean that...

I don’t have adapter boards, but I do have 2 jfts left. Can I use cut off component ends to make them through hole?

I have reflowed a few times... also had a pack of 5 smd jfts from pedalpcb. I went in and replaced the first one. Is it possible to have...

Def feel like there's some issue in that bias/jfet area...esp if the voltage is the same at all poles of the jfet and the bias pot isn't...

All cleaned up and still no effect signal... passes fine.

I'll clean it up... def needs that. Can excessive flux cause shorts? I should probably know this :)

I took the switch off, took the pcb off, and reworked it just to make sure there wasn't a short on the switch. All works fine. When you...

Just measured: one probe on the plus of the socket coming in and the other probe to each of the ends of the J201. JFT 1: G: 8.5 S: 9.2...

Not pretty! But I've reflowed and checked between solders for bridges. Also, I left the legs on the transistor for now.

I know this is prob a low priority, but if anyone has any input I'd appreciate it. I looked at the voltages to the Jfet last night and...

Also…if you’ve built one and biased it to spec, go back in and do it by ear just to see. I just went back in and found that i liked it...

Also…ground to pad gives me 9v, but when I try to bias the jfet—just to see if I could—i get nothing. Is the jfet maybe not grounded?

@Robert I did more testing and was able to trace the 9v through to the end. Not sure what the issue was before. Still, the pedal isn’t...

Just one end. Should it be passing through? That may be it...
