DEMO Figment Preamp (Acorn MIGFET 50P)

[owlexifry]

Is there a certain number that’s important when matching these up for this particular pedal? Any recommendations here are greatly appreciated. Thanks!

i have no idea what the ideal specs are, but this is what i did

measured a few mmbf5457 jfets and selected x3 that rated around -1.5V (Vp) and ~3 ma idss

(using a multimeter & this circuit)
