RUNOFFGROOVE: Nurse Quacky (EHX Dr Q)

Runoffgroove Nurse Q vero layout b175d577e7ad

This one seems to have many parents – I was not really sure what to tag it as.  It started life as an Electro-Harmonix Dr Q, which ended up as a Jack Orman Dr Quack and then at some stage Mark Hammer mods have appeared, and more changes bought it to Nurse Quacky by Runoffgroove.   Hopefully … Read more

D*A*M: Ezekiel 25:17 Low Frequency Distortion Generator, 0.15″ Vero Layout

DAM Ezekiel 25 17 vero layout v2 aca84ef8f578

REVOX: A77 Input Amplifier Clean Boost, Overdrive / Light Fuzz

REVOX A77 61f0fa4ffd0e

This is the input amplifier from a Revox A77 reel to reel (circa ~ 1967) – which also happens to be almost identical to the mic preamp in Trident A-Range mixing consoles from the early seventies. So far out of the preamps that I’ve been working on, which is the Neve, RCA and this, I’m … Read more
