Our JFET Preamp was originally based on a circuit used by Scott Hampton in his HAMPTONE JFET preamps.
HOMEWORK: Read Scott's
Article and draw the simple JFET 15 times
we are using that details how the gain and limit pots are connected

Prototype in progress. The circuit is a morph of Scott Hampton's JFET and the Pultec MB-1 (vacuum tube). It can be mono or stereo. Mono version has a buffered loop through so Instruments taken direct can drive pedals and amps without affecting tone. Both mono and Stereo versions have optical limiting. Need to finish this mono version and build a stereo version to confirm that there are no mistakes, which so far I've only found one! Then, I need to design a front panel PCB and redesign the front panel.
