guitar boost ?

[Jamie]

Before this post gets moved to the dead letter office... is there away to add a signal boost/fat on a guitar with bridge, neck, one volume , one tone ?

[phsyconoodler]

Yes,but it involves adding a battery and a circuit to increase the signal strength from the pickups.
   An opamp and 9v battery and some circuitry.

I ask this because a friend wants me to "restore" the wiring in a messed-with 60's Tiesco , that HAD some switched boost function... he seems to remember it as adding more bass/bottom.

Unless it had a battery it was probably taking away bass bottom end rather than "boosting it".

i don't know where i saw it, or what it is called, but there is a mod out there for passive, onboard, guitar boost. baiscally it is a diode clipping circuit - one diode or two, perhaps with a cap to round off the corners.

[tubesornothing]

without a battery, and hence an amplifier - it ain't a boost.  A passive diode clipping circuit will not boost the signal, it only clips it (hence the name).

If they call it a boost, its a misnomer.

my bad. i was addressing the inquiry for 'fat' more than 'boost'; where a signal lightly clipped by a diode and smoothed by a cap would sound 'fat'.
