This is the LFO / modulation section from the Keeley Magnetic delay – I will try attaching this to the Earth Quaker Devices Disaster Transport Jr, and hopefully get some tape-like warble happening.  They’re both PT2399 based delays, so in theory, this should work.

GHOST EFFECTS: Lunar Incantation, 0.15″ Vero Layout

Just putting together some options for some leftover 0.15″ vero – and I was going to do a standard Fuzzrite, but I ended up doing this instead – which is of course the Ghost Effects Lunar Incantation. GHOST EFFECTS LUNAR INCANTATION – 0.15″ VERO LAYOUT GHOST EFFECTS LUNAR INCANTATION VIDEO DEMO

ZVEX: Machine

This is an interesting one – the Zvex Machine uses Mosfet boosters into a pair of transistors in a push-pull configuration designed to generate cross-over distortion.  Apparently, it doesn’t do much on its own but likes to be paired after a fuzz to shine.

ABY Amp Switch Box

I recently tried building an ABY box with isolating transformers on the outputs, and I just could not get it to work (well, everything worked, apart from the constant buzzing that I could not get rid of, which was incredibly frustrating).  I then pulled out most of the components, just leaving the switching and LED indicators, which … Read more

FOXX / AION: Tone Machine / Vulcan

After recently finishing a mojo size / vintage transistor Tone Machine that has been sitting on the bench for way too long, I decided to do a regular layout, as the practicality of some of my other layouts for the Foxx is probably not for everyone (maybe even me in retrospect). So I’ve done a standard … Read more

HUDSON ELECTRONICS: Broadcast, Peach Guitars Version

This is the Peach Guitars version of the Hudson Broadcast, as traced by V1nce69 and posted on the Guitar FX layout forum.  Others also did work on tracing in this thread, so sorry if I left anyone out.  Lots of great gut shots and a bunch of measured voltages there too. The layout is basically … Read more

UNKNOWN: Parametric EQ / State-Variable Bandpass Filter

I found this schematic a little while ago and thought I might give it a try, as I’ve been looking to make a single band parametric equaliser, in this case, based on a State-Variable Bandpass Filter.   It’s supposed to be from a Japanese textbook, but I’m not sure of its origin.  It looks remarkably similar to a … Read more
