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
The Death by Audio Fuzz War V1 is notoriously hard to build by all accounts, which makes me want to try. Might breadboard this one first to sort out any bias issues before committing to the board. DEATH BY AUDIO FUZZ WAR V1 – VERO LAYOUT
Update 2 210514 Both schematic and layout is now corrected. A big thank you to Vince who traced the later 125b version which revealed how the active Mid control really works. Update 1 210514 Caution! There was a mistake in the trace. The Mid control have a different setup than the schematic and … Read more
Happy Fuzz Friday everyone! This one recently got traced on the Aion blog (so go check out the full write up over there for more info and schematics). The Karma Suture is based on the Harmonic Percolator and has come in both germanium and silicon versions. The difference between the two are just a couple … Read more
Just a little reference to Soviet-era transistor pinouts. SOVIET TRANSISTOR PINOUTS note: in addition to potentially different pinouts, some Soviet-era transistors can have the case connected to the base – which is not good if it touches anything else. The dot on the case usually marks the emitter, not the collector as often found on European … Read more
A slightly modified Tubescreamer with the input buffer replaced by a SHO MOSFET booster. The Calibre control can be noisy but I guess “Crackle is OK”…. Schematic is avaiable HERE.
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
Traced by AlexS and Fuzzhead, this is a quite tweakable and heavily modified HM2 variant with more gain on tap, more volume, two on/off/on diode switches and a very flexible four band eq. It is a quite noisy beast when Gain and all eq controls is maxed out though but a buffer up front helps … Read more
It is Pie Day so here is a layout of an old Ram’s Head variant. Rarely cloned and some cap values is not found in any of the other vintage EHX variants. 220pF/680pF caps replaces the standard 470pF/500pF values and the tonestack has less mid scoop. Still added a Mid switch for some sligtly boosted … Read more
