Gibson Nashville Circuitry

[bea]

Hi there,

in its ES 339 Gibson advertises a "Nashville Circuitry" compensating for the treble loss if the volume is turned down. Does someone know about the details of that cvircuitry, especially if it is more tricky than the well known treble bypass capacitors (we need two of them, don't we?).

Thanks

Black Rose circuit

The Nashville circuit sounds familiar, but I don't know it specifically, I do know the Black Rose circuit does exactly what you want.. have done this one on a Dot epi and an Epi LP. I don't lose trbl when the vol is turned down, I also put in some loading resistors on the pickup leads at the switch to allow independant vol adjustment all the way down, no cut off of the other pup with little sacrifice of vol. Hope this helps...

Well,there is the treble/resistor network across the vol pots.

Then there is the Varitone.

Similiar but different...

The resistors on your diagram with the cap across is a pass filter of sorts( treble bleeder ? ), the resistor I placed on the switch was in series with the pickup only, loading it enought to prevent the Parallel Gibby Syndrome, one vol shuting off the other...I'll see if I can find the link. http://www.guitarnuts.com/wiring/stockgibson.php

Seems to be a treble bleed cap:
