an easy to build FUZZ
this one here's an adaptation of P. Hemmo's modern Bazz Fuss fuzz. low parts count, massive tones. you can swap out the output cap with a 1uF cap for more low end.

An ENVELOPE FILTER project
Ah, the good old envelope filters, expressive little boxes of wah-wah goodness without the treadles. Basically, the envelope filter sweeps a certain range of boosted frequencies that is triggered by detected envelope of a string's initial attack. Pretty nifty.
The following is the Nurse Quacky project (which is a bit tweaked EHX/Dr. Q circuit). Original circuit by the good guys of Home-wrecker.

PSYCHE1: A simple VIBE pedal project
The following is a simple Vibe pedal project consisting of a unity gain stage and an oscillator driving an LED (light emitting diode) and LDR (light-dependent resistor) to generate a single stage 180degree phase shift.
I omitted a depth control since it has fairly minimal use, but you may opt to install one just the same: simply use a 25K potentiometer in place of the 30K bias trimmer.
Its effect is very subtle, and many like the circuit for this characteristic, as opposed to the usual balls-to-the-wall effects that some use.
