This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Run Off Groove Condor Cab Sim

Part of the last request included a cab simulator to run the headphone amp through. The ROG Condor is a great cab sim and has a fairly low parts count. It uses a JFET amplifier at the input, boosting the signal to drive the following 3 filters (Bridged-T notch filter, High-pass filter, and Low-pass filter). Much more info on the circuit can be found here, as well as a few mods. J201 apparently sounds the best for Q1, but similar DSG pinout JFETs will also work. Any dual opamps can be used for the 2 ICs, so socket and try the usual candidates (TL072, JRC4558, etc).

    1. You'd still need something like a direct box to go to the PA, but theoretically yes.
