The OR120 pedals will come in two versions: a 125B sized pedal without the FAC switch (a 6-position rotary switch that progressively filtered out the low-end) or a 1590BB sized pedal with the FAC.
I'm planning to do the GT100 in three flavours: 125B with no FAC (or Bass Boost as I think Matamp called it); 1590BB with FAC and a larger version with the FAC and Drive rotary switch.
These three circuits are the proof of concept prototypes and are currently pretty damn close to the originals, save for the JFETs! Both the '72 OR120 and GT100 boost circuits contain inductors, just like the original amps.
I can't wait to get these into testing phase!
