Does anyone have a link to one? I'd like to build a tiny 3-band eq that I can mount in my control cavity. No bells and whistles, just something with 3 trim pots for bass/mid/treble cut. I just want something that I can dial in to make a bridge pickup sound closer to a neck pickup with the flip of a switch. My initial plan was to use a tone switch, but an EQ that I can tweak would be better.

Also, I'm a novice at this stuff, so any advice is appreciated.

For a 3 band eq the insertion loss will be high so you'll need a gain stage befpre and after the tone control section. as for schems, look at a diagram for pretty much any fender amp.

You can also get Duncan Tone Stack Calculator.
Its basically a tone stack calculator and simulator.
It has several different tone controls and lets you mod them and simulate it.

Ah that's what I was afraid of. I'd prefer to just buy something if it's going to be complicated to make, but every onbard EQ I've seen is large and obvious.

Wow, that's pretty awesome.

Its not really complicated per se. the parts count will be a bit higher though. a simple one-transistor or opamp gain stage before and after will do.
