KAY UNIVOX EFFECTOR FUZZ

[SpencerPedals]

No chromed plastic on the one in the picture I attached, only chromed steel or brass.  The arched top is indeed laminated, and there's a ply reinforcement where the bridge attaches, but the solid back portion that comprises most of the guitar body is actually not laminate.  That's solid mahogany.  I have all of the hardware and neck removed (neck is getting a refret) and all wood is plainly visible.

Sorry to resurrect this topic, but I'm trying to create a fuzz pedal of the one in the Effector circuit. I have drawn a schematic, but I'm not sure that it is correct. I'm hoping that someone here may be able to confirm or correct my drawing.

Thanks!

For unity gain make R4=R3 (at the expence of max gain..)
R100 might be ommited (although it makes no harm..)

There is no connection for the second half of the TL072 and without applying fixed bias within the active input range, the second section can oscillate.  In this circuit, you could use a TL071 but if you want to use a TL072, connect the unused op amp with the non-inverting input to the non-inverting input of the active section and connect its output to the inverting input.
