Plexi-Drive with Trimmers

Yup. Most of you who know me know that i've had more than enough trouble with JFET biasing on some fixed drain resistor designs... This one also has the input cap and pulldown resistor at the input. Already verified by me. I found the best gain to be with drains at ~5V, but now you can tweak them to the voltage you want. Used 20K pot for tone. 50K should be fine too.
