The Pete Cornish ST-2 is a Colorsound Overdriver with a few mods. The ST-2 is intended to be a tone-shaper; it’s not actually an overdrive. So if you are looking for dirt, you have come to the wrong place with this one. Although one can make a few tweaks to bring some dirt to this, but … Read more
Like the very lengthy title below suggest, it’s a Pete Cornish SS-2 with mods. After finishing the SS-3, they’re almost the same, so I thought I would also do a SS-2 layout. Changes Swapped the Cornish buffer for a standard opamp based buffer Ran the reference voltage through the spare opamp Used a quad opamp … Read more
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
The Grand Orbiter Phase Machine is a four-stage OTA phaser, with options for vibrato or phasing (a bit like a Univibe). Not exactly a small board, but not too much to take on either. MLC caps might be a good idea for some of the 1uf caps to save space. Currently unverified. I have reviewed the … Read more
A classic phaser from the mid-seventies – the Musitronics Mu-Tron Phasor II. It has the same six-stage phaser as the Bi-Phase, with less happening in the oscillator section. This is the hardest layout I have ever done and took some time to finish and check… including some time wasted after I started using a layout with … Read more
I’ve already built the Micro V, and it’s a really cool-sounding envelope filter, so I thought I might try the Musitronics Mu-Tron III. It’s generally regarded as THE envelope filter of its day. As much as I love a bit of fuzz, I really do enjoy sitting in a groove with an envelope filter running…. Note … Read more
The MXR M-103 Blue Box is a sub-octave fuzz (two octaves down). It’s not a clean sub-octave either, pretty dirty really, well it’s a fuzz… kind of synthy on some settings. Might want to check how many 56k resistors you have before starting this. MXR BLUE BOX – VERO LAYOUT BLUE BOX OCTAVE MOD Same … Read more
Nothing to see here – just a Marshall Blues Breaker… quite the classic today, bit did not do well when it was released. MARSHALL BLUES BREAKER – VERO LAYOUT
Like Tube Screamer overdrive, but hate the Tube Screamer mid bump and lo-cut? Then the Yamaha OD-10MII Overdrive might be just the thing for you. Schematic at Aion YAMAHA OD-10MII OVERDRIVE – VERO LAYOUT v2 corrected VIDEO DEMO
This is the Rene Schmitz version of the MS-20 Filter, which is used in the later models. I didn’t include the CV control inputs, as I have no plans on using CV. KORG MS-20 FILTER – VERO LAYOUT KORG MS-20 FILTER – BUILD REPORT This is a very particular sound, and while it doesn’t have a lot … Read more
