Simple Baxandall Ciruit in a Guitar

[frets]

Hi Fellas,
I’ve been working on a 100w Class D amplifier for my son in order to build a stereo for him (Trag will like that news). I built a Baxandall tone circuit for his bass and treble, it also has an EQ I built. So lots of tone.

Anyway, how this relates to guitar-Ihooked up the Baxandall to my tester guitar for the heck of it and was quite surprised. It sounded pretty good, kinda like a G&L but kinda not (I know, not real scientific).

Just wanted to know if any of the group has actually put one in a guitar or pedal? Or tested it in Guitarfreak. One side is a little heavy but that could be lightened up. I’m thinking about tweaking it and putting it in one of my Partscasters.

So, any of you guys messed with one of these?

BTW - In the stereo so far, this circuit is pretty acceptable given it’s completely passive.

frets,


For a rather spirited discussion on the Baxandall circuit, we all worked in concert to successfully hijack trag's "Whachu workin' on t'day?" thread. Go here for the starting point, and work your way along until it peters out.

frets if you like it, then it is likable!

But we don't normally see them in passive guitars. The main reason is that as a passive circuit like that, it is inherently lossy, ie, setting aside tone, the output volume is inherently significantly less than the input volume.

Also, it loads down the pickups reducing their upper sparkle, although values could be adjusted to help that.

The beauty of the G&L PTB circuit is tbat it gives a good measure of treble and bass control, but with no loss of signal level when at max.

X=250K and then 56K for ever location on wards will replace the C1M in a G&L circuit
Bypass - 250K - 56K step ups - 1034K 
dont forget the 2n2F caps
