Details of this project can be found here – as I started with a modded Pete Cornish SS-2 using the Joe Davvisson diode-compression op-amp, and then moved on to this. Essentially the same as the SS-2, but with the addition of a lo-cut. After a bit of testing, I’d suggest a C50k for the sustain … Read more
Since I’ve been on a bit of a Harmonic Percolator thing lately, I thought I might do some 0.15″ mojo layouts using Albini / Mad Bean Pepper Spray values. Here’s one built by Sean of Spiller Instruments. Looks great, as do his other builds. INTERFAX HARMONIC PERCOLATOR, ALBINI VALUES – VERO LAYOUTS
A somewhat polarising classic – the Boss DS-1, with a slight twist, as this has the Joe Davisson discrete diode-compression opamp onboard instead of an IC. BOSS DS-1 DIODE COMP OPAMP – VERO LAYOUT BOSS DS-1 DIODE COMP OPAMP – WAMPLER STYLE JCM MODS This is what I ended up being happy with on the … Read more
Silicon version this time, as it was pretty similar to the hybrid silicon / germanium version. Link to schematic Link to tracing journal on Aion FX CATALINBREAD KARMA SUTURE, SILICON VERSION – VERO LAYOUT VIDEO DEMO
A nice Harmonic Percolator variation from Catalinbread. They’ve kept the bones of the original, and have added an input capacitor blend, as well as a pot to dial in the diodes on the output. Link to schematic Link to tracing journal on Aion FX – and think about buying one from Aion CATALINBREAD KARMA SUTURE, GERMANIUM VERSION … Read more
This one has been requested for some time but since there was no confirmed schematic avaiable I didn’t want to pull the trigger. But Aion Fx just uploaded a schematic with their Termina project. It also includes a trimpot which affect the bass response and clipping. Schematic and more info is avaiable HERE.
Haven’t done a tag board build for a while – so here’s a classic. INTERFAX HARMONIC PERCOLATOR HP-1 – TAGBOARD LAYOUT Being tag board, I’ve used 1/2w resistors and axial caps. You could use something more practical (smaller), but if that’s what you want to do, I would recommend using a different layout, as this is … Read more
After doing a layout for the Nordland Overdrive, I thought I would compare the differences to the designers original Nobels version. Apart from some insane power filtering / protection and LED circuitry, there’s a couple of small changes. Traced schematic for the Nordland is here, on Aion FX Hard clipping diodes to ground, instead … Read more
