Buffer idea for higher gain amps

[Gus]

A different version of a circuit I built for a friend some years ago
This is a bootstrapped buffer sim with adjustable low end resonance (not built this is a sim)

I built a high input resistance gain stage x1 on up to a volume attenuator

My friend was using a 5150 and wanted to use the resonance of the guitar/cable/amp input resistance with the volume control turned up on the guitar but not hit the first stage too hard.

So the circuit at low gain buffered the guitar and resonated with the guitar with the volume turned up, cable, >1meg input  resistance

AND this conditioned guitar signal could be turned down at the output of the buffer gain stage so the first stage of the 5150 was not "seeing" as hot a signal.  My friend did not want a cap from in to wiper on the volume control

If you turn down the volume control of a guitar without a bright cap on the volume control you can lose the high end resonance.  R8 at 50k and R11 at 200k in the sim

R5 and R13 are one 10k volume control

I like the way you setup that schematic. It describes how the circuit works. Nice!

awesome. there is so much to be gained in the components between pickup and amp, even w/ no pedals present.

there are a whole bunch of  guitar techs for touring pros who have their own recipes for treble bleed circuitry, for example. we don't read about it online because they are too busy on tour and also don't want the world to know their secrets.
thanks gus, i like it!

Looks interesting. Dropping some level before high gain is often a good thing.
Then there is the EQ bump...neat.
