Well, I tried to repair the jfet at Q2. It's the first jfet in the middle going up. Packed the little stub with flux and verrrrry carefully aligned everything and just gave it some solder.
Stayed together, no working pedal, just some staticky frottements. I checked continuity to ground, continuity to vref and vcc, and continuity around the transistors and the socket everything looked good. I banged on the enclosure a bit to see if anything could shake the signal loose. This time I had a tiny bit of signal with all pots open. But, q2 broke loose again.
So I decided to bite the bullet and figured it just could be the smashed q2 causing the circuit to limp, so I decided to sacrifice another one of my Gucci j201s to the Sabbath tone.
Desoldered the old one with a minimum of collapses (PtoPers feel my pain), bent and fit things to make the new one match, keeping in mind what I learned not to stress the body juncture of the jfet legs and know I had to do it in a gentle minimum of bends and light light solder touches and......
....I have a churning raucous Sabbath/doom machine (!!!). Great pedal!
I guess the pedal gods verily heeded the incense and anointing of the holy troubleshooting apparatus.
Here is the pinup soft focus final incarnation. New q2 is the mustache looking one right above the socket. Less pretty than when I first laid it out, but I am so grateful it works! And it's my prettiest pedal to date (which ain't saying much but still...). I might audition some higher and lower hfe npn germanium transistors at q1--2 of the 3 I ordered have hfe in the 400s--but for now i am happy to let this little buddy rest.
