Includes schematic and PCB layout for basic DIY pedal hardware. This includes two 1/4" jacks (one for input and one for output), a 9V power supply (including LED), a 3PDT true bypass wiring setup, and an example potentiometer that can be copy/pasted throughout the circuit. The headers are meant to be unpopulated so that wires can be soldered to the pads. PCB design rules imported from the JLCPCB 2-layer stackup template. #template - [Pedalboard Headphone Amp](https://www.flux.ai/jwwitherspoon/pedalboard-headphone-amp.md) - Stereo headphone amp meant to fit in a pedal enclosure for use on a pedalboard. Buffers the signal, then splits it to an output meant to go to a mixer and a headphone out. The headphone amp circuit is applied to the signal before the headphone jack. Originally designed to give the ability to run effects after an amp simulator pedal with no effects loop. Example chain: amp sim > wet effects > headphone amp > mixer.

Designed to be an onboard amp for an instrument with a speaker in the body. JFET buffer replaced with op-amp buffer from Jack Orman because JFETs are currently hard to find. LED is dimmer than the original because my eyes are sensitive. ☀️ http://beavisaudio.com/projects/noisycricket/ https://electrosmash.com/noisy-cricket-analysis - [Hull Fuzz](https://www.flux.ai/jwwitherspoon/hull-fuzz.md) - Schematic/PCB for the Hull Fuzz circuit designed by Amir Akhlaghi. Link: https://www.facebook.com/share/p/1BiELj24wj/?mibextid=wwXIfr - [Bazz Fuss Variant](https://www.flux.ai/jwwitherspoon/bazz-fuss-variant.md) - My version of the Bazz Fuss, a popular DIY pedal circuit. Includes a switchable buffer in front of the fuzz for crazy, treble-y goodness. Also includes a pickup simulator between the buffer and the fuzz. The pickup sim can be used in tandem with the buffer to use the fuzz's non-buffered sound at other points in the signal chain without undesirable consequences. - [SPDT Toggle Switch on-none-on](https://www.flux.ai/jwwitherspoon/spdt-toggle-switch-on-none-on.md) - Through-hole and panel mount SPDT toggle switch. - [RV16AF-41](https://www.flux.ai/jwwitherspoon/rv16af-41.md) - A potentiometer with right-angle PCB pins.
