I am close to finishing my Sandspur fuzz https://www.pedalpcb.com/product/pcb378/

with these BC108 https://www.taydaelectronics.com/bc108-bc108b-npn-small-signal-transistor.html

You can do it using a DMM or by ear. I assume that you turn the bias trimmer fully CW then the sundial should be at 12 as a starting point. You can bias it by ear on the sundial trimmer to what sounds best to your ears.
