Mesa Boogie Mk. 1 Preamp
A verified layout by Sebastian, thanks mate! In his own words… I forgot about this layout I did ages ago, built up (it works), and never got around to boxing up: a Mesa Boogie Mk.1 preamp. I’m personally partial to pre-gain tone stacks (e.g. ’60s Fenders, Orange Graphic MkII), so I was disappointed with … Read more
BELL & HOWELL: Filmosound, Model 156
This one turned out to be slightly different to the others I’ve worked on – it’s a Bell & Howell Filmosound, Model 156 Projector Amplifier (Part No. 13817), field-coil speaker version.

GUILD / CORNISH: Silicon treble booster
As I was recently playing around with the Colorsound booster made by Steve Williams of Pig Dog fame, I noticed some similarity to the Guild Treble Booster, AKA the Brian May Box. I made a slightly simplified version of the Guild, without the buffer based on one of the Fryer Boosters. I kind of free-styled … Read more
ELECTRO-HARMONIC x JHS: Big Muff 2
It’s been a while – and I’ve probably scared most of you away with obscure amp content, but I have to have a crack at this one. Yes, it could have been a smaller layout, but to be honest, I’d still be adding some room around the edges for proper mounting points. I also … Read more
