iCircuit Seems To Work With The Classic Matsumin 12AU7 Overdrive
Man! I so want to build one of these! A tube distortion pedal that runs of 9v. The legendary Matsumin Overdrive, origins are quite sketchy, but commonly reproduced as the DIY "Valvecaster." I guess Matsumin was probably either a Japanese engineer in a small amplifier and and electric guitar factory, or a dedicated hobbyist. The origins are probably the 1960s. A software simulation of the Matsumin Valvecaster overdrive pedal. I know, you're like, "Wait! What?! That's running on 9v!!! A tube circuit?" Well, yes it is 9v, and no, it's not a bug in my iCircuit instance. It's called "starvation mode" amplification. I can't find much about the concept of starvation mode online, other than this circuit in its many, many variations, but my best guess is it's something to do with that thing that happens with some tube amps where, when you turn them off, the volume drops as the power supply filter capacitors discharge, then briefly "bo...
