Tools, Tones and Toys for Guitarists
I started this layout ages ago and never finished it for some reason – anyways, here it it, the Univox SQ-150 Square Wave. Mark Hammer mods included below. UNIVOX SQ-150 SQUARE WAVE – VERO LAYOUT UNIVOX SQ-150 SQUARE WAVE – MARK HAMMER MODS – VERO LAYOUT ORIGINAL SQUARE WAVE SCHEMATIC
Here is another trace by evilarsen; Fuzzlord Drone Master. It is essentially a tweaked Rat with a diode selector switch, a switchable twin T notch filter for a mid scoop a la Superfuzz, and an op amp output buffer. There is two versions for this (2019 and 2020) and since they differ quite a bit … Read more
So I just worked out why I purchased some Motorola MC1748CG tin can op amps – it was to make one of these. I’ve had them in my parts draw for a while, trying to remember what they were supposed to be for. I thought maybe the Hudson Sidecar, but no, I need a dual for that. Anyways, here … Read more
OK, so this one is wide even by my standards – but it will still fit in a 150BB in landscape format. I could have made it a bit smaller, but once you get past a certain width, why hold back is my theory. The Gretsch Play Boy Harmon Booster was one of my early … Read more

Happy Fuzz Friday, everyone! Here’s a cool take on the IC Big Muff by JuanSolo and Grind Customs. It’s essentially the ’78 IC Big Muff with the tone bypass switch with the tone stack from the Ultrastoner. Should be able to squeeze it into a 1590B.
A portion of this is based on the limiter circuit in some of the Thomas Organ Vox Beatle amps, which were solid-state amplifiers. This was meant to protect the power amplifier section from overloading – R.G. Keen has explained it way better than I could here on Premier Guitar. So far, I’ve only tested the … Read more
Turned out a bit big but it will fit in a BB enclosure… Based on the schematic avaiable at PedalPCB.
