Dynamic magic under your fingertips …
A step in the right direction perhaps, this time using a soft switching approach to opto-controlling the gain level in my original (non-linear) “Triode emulating” booster design // unlike my previous true-bypass builds which are naturally prone to switch “popping” – the drawback of NL output
Briefly, this circuit replicates the large-scale non-linearity of a vacuum Triode voltage gain circuit, the same kind used in vintage tube circuits (Fender, Marshall, …) It is *very* good at waking up old low-gain vintage tube amps, and some users report having the pedal on all the time as it takes a very natural seat in the gain structure of an amplifier chain …
The switcher allows going between unity gain and variable output, capable of delivering considerable boost levels (x11 or more), with added pick “edge” sharpness and squeaks … Rory woulda dug this I believe & much less noise than a Rangemaster //
