PROCO: Rat, with mods

PROCO Rat with mods vero layout V1 c85432703782

The humble Proco Rat – a staple of distortion throughout the 80s, and then later rediscovered by people that couldn’t afford expensive pedals or just liked the sound.  By the way, I refuse to acknowledge the Rat as a fuzz pedal.  Others may, but not me… Excellent analysis on Electrosmash if you have somehow missed it – link here  The … Read more

PETE CORNISH: ST-2, Modded (Simplified)

PET CORNISH ST 2 mod vero layout v1 14bbf1e73b4b

This is a simplified version of a Pete Cornish ST-2 (based on the Colorsound Overdriver).  I did the full layout, and it it kind of large, and double buffers are not for everyone. So no buffers, and the power supply filtering is simpler.  I’m sure the proper Pete Cornish version is probably better, but if you prefer something smaller and simpler, … Read more

PETE CORNISH: SS-3 Soft Sustain, Vero Layout, Buffer Mod

PETE CORNISH SS 3 vero layout with buffer mod v1 f164d482c0a9

The Pete Cornish SS-3 is one of my favourite overdrives – so I thought I might make another one with a different layout and buffer. Changes Swapped the Cornish buffer for a standard opamp based buffer Ran the reference voltage through the spare opamp Used a quad opamp instead of 2 x single op amps … Read more

BENSON: Preamp, Dylan159 Modded

BENSON Preamp modded vero layout 9f402dafa9fb

This is a modded Benson Preamp by Dylan159 on Freestompboxes.  Dylan has taken the original and simplified it but has retained the overall character.  Quite a detailed explanation via the link above, including a schematic, LTSPICE model traces, audio and his vero layout.   What a solid effort. For me, this is useful, as it has a standard … Read more

BALDWIN-BURNS: Buzzaround Timbre Mod, Schematic

Buzzaround timbre sweep mod schematic 68eb7ca19108

A simple mod to provide more flexibility for the timbre range of the Buzzaround. One side of the timbre control is 15khz high-pass filter, which is very high.  The useful range of the timbre sweep is rather limited as a result of this, and there’s also a bit of volume loss that comes with this. Some D*A*M … Read more

UNIVOX: Super Fuzz, Notch Filter Mod

UNIVOX Super Fuzz Notch Mod Vero Layout e449b4c14bdb

This is a handy little mod for the Univox Super Fuzz – especially for those who always leave the tone switch on the notch setting.   Instead of a tone switch, there’s a pot from the 100n capacitor to ground in the bridged-t notch filter, so the amount of notch can be dialled in.  If you really want … Read more

ROLAND: BeeBaa AF-100, Point to Point and Vero Layout (Modded)

ROLAN BEEBAA STRIPPED BACK 0de115afc746

This is a bare-bones Roland BeeBaa.  I built the full version and found that all I really used was the scooped fuzz sound – so this is just that.  Nothing but unadulterated vintage Japanese fuzz….     I think this works best with low-gain transistors.  I made a version using weird KT315 Soviet BCE transistors, and it sounds mean.   … Read more
