Tools, Tones and Toys for Guitarists
I’ve posted layouts for a stripped-back version of the Roland BeeBaa, but never for the full BeeBaa. So here it is. The Roland BeeBaa has a couple of extra options, not generally found on fuzzes of the era, mainly the treble boost and tone control. The switching swaps between a treble boost and a fuzz … Read more
Check out the video, as it includes a tear down, schematic and a great explanation of the Barber Edge Hog circuit by Gray Bench Electronics. He has a few other video that are worth a look too – hopefully more traces to come… BARBER ELECTRONICS EDGE HOG – VERO LAYOUT note that I did … Read more
Be prepared for some scorching output level – the Saturn V is LOUD… SPACEMAN SATURN V BOOSTER – VERO LAYOUT SATURN VIDEO DEMO
After some success with the Trident mic preamp (AKA the Revox A77 Preamp), I thought I might try another section of the console – this time the EQ / Channel output amplifier. It looks interesting on LTspice, as towards the end of the gain range, you get a distinct bump in the mid-range. At the moment I’ve … Read more
There’s a massive thread of modded circuits at Free Stomp Boxes by Dylan159 – this one is a Bazz Fuss / Fuzz Face hybrid, suitably called the Bazz Face. There’s plenty more in the thread, including schematics and sound demos. DYLAN159 BAZZ FACE – VERO LAYOUT BAZZ FACE SCHEMATIC Drawn by Dylan BAZZ FACE … Read more
Another fine circuit from Jonny Reckless, this time he’s headed into cranked Marshall territory (hence the name). Here’s the thread on DIY Stompboxes RECKLESS LITTLE JIM – VERO LAYOUT RECKLESS LITTLE JIM – VIDEO DEMO BY JONNY

Like others, I had read the hype about the Vox Pathfinder 15R and thought, really? I’d never paid any attention to them until I saw an article in Premier Guitar recently. So when I saw a Vox Pathfinder 15R pop up on Facebook marketplace at a reasonable price, I thought it would be worth a shot. … Read more
A variant of the Matsumin Velvecaster, the Frequency Central Valvemaster. I really like Valvecasters, so I was looking forward to making this, but it just wasn’t working for me on the breadboard today. I might try a different valve / test the valve I’m using in a valvecaster circuit just to make sure it … Read more
Another one from Jonny Reckless – the Moon LNDer distortion, using LND150 MOSFETS. All the required details can be found on DIY Stompboxes, including schematics, some suggested mods and a video demo with a few words from Jonny. Set drain bias to between 6 and 7 volts by adjust the 10k resistors going to the … Read more
