This is a JFet guitar pedal that is based on a peavey 5150 preamp i got the schematic from: www.techniguitare.com and i made a pcb from this:https://www.fichier-pdf.fr/2010/04/13/08zhzj8/pdf-5150-v1-31.pdf
A collection of analogue effects processing circuits.
These are simulations and not complete designs but will take relatively little work to turn into finished designs that can be transferred to PCB.
More work is required on things like the input buffering, pre-amplification and gain or tone controls, output buffering and mixer stages and power supply (the simulations are all based on a split +...
fuzz tonebender vox clone with charger pump. Pedal can be powered by external power supply and can be used in chain effect. typical gain for OC75 transistor are 70 hfe for Q1, Q2 and 100 for Q3. Great thank to fuzz central website and his remarkable job. http://fuzzcentral.ssguitar.com/index.php.
