Tools, Tones and Toys for Guitarists
This one has been requested for a while. There seem to be several versions of this circuit so I guess we should start with V1? There is several schematics online, all of them have different wiring for the Bass and Treble controls. So the lug numbering may need some corrections.
The stock Rumble Fuzz suffered from not being loud enough. Dead End Fx decided to take care of that and added a J FET booster after the Volume control (it is labelled “Fuzz”, not sure why….). The layout below is verified and this is now a loud, hairy, air moving fuzz indeed. I used a … Read more
Had an unverified layout in the library that I was quite unhappy with so I decidied to give it another go with a new one from scratch. This is a soft clipping overdrive with a bass boost and cut filter. The eq / filter section are pretty unique with an OTA LM13700. With the Depth … Read more
A bit hesistant to upload this one since there is an unknown cap value and pot value. But a quite a few people have requested this one so I guess a 95% accurate trace is ok? Traced by evilarsen, AlexS and myself. It is a Rat based circuit running on 9v/-9v up to 18v/-18v. It … Read more
A forgotten and quite odd one from the early days of EHX. Despite being marketed as a “Microphone Echo” and having “Echo” as one of the labels for the controls, this is actually a tremolo circuit with some quirks. There is no “Depth” control as in most tremolo effects, instead there are the “Echo” control … Read more
A simple and nasty octave up fuzz based on Tim Escobedos Push Me Push You fuzz. But here, the input transistor is replaced with a LM386 audio amplifier for more gain that pushes the transistors harder. Also, there is also a simple treble cut tone control added.
