High pass tone knob for guitar???

It annoys me that I can roll off the highs from my guitar, but not my low's... If I added a 250k pot and a capacitor (.22) in parallel between the output jack and the volume pot would that give me a 'treble' knob?

The tone control on my guitar now has the output run through a 250k pot and .22 capacitor in series to ground (which is standard) so the capacitor shunts the high frequencies to ground when the resistance of the pot is lowered, but if I wan't less bass???

I had some electronics courses a long time ago... it's all fuzzy now... I think this will work but I'd like some other input before getting out the drill... Maybe I can test it by making a stomp box...
 
I just read this in a Bass guitar forum:

One of the 'secrets' to the sound of vintage Ricks (besides the toaster pickups) is that most 60's Ricks had an extra 0.0047 microfarad capacitor attached between the bridge pickup and its volume control. It creates a high pass filter, giving the guitar more bite. The mod can be done to any guitar.

Interesting... Add a pot in parallel, and you can shunt the cap, thereby bypassing the 'filter'... That's my theory, anyway...

Get a TBX control from Fender. At the center detent it is flat. If you turn it down, it acts like a normal tone control (i.e, a low pass filter), but as you turn it UP, it is a high pass filter.

Cool. I wonder why guitars don't have that ablilty stock... This IS friggin 2007, you THINK there would be a TREBLE knob on guitars by now... :)

Thanks, Light :)

Well, first of all, it IS available on some guitars (the Eric Clapton Strat, and some of the other high end Strats - hey, they have to differentiate them somehow), but the main reason is that it isn't traditional, and guitar players (for the most part) are a hide bound lot.

Oh, and I use one as the tone control for my bridge pickup in my Strat, for what little that may be worth.

God, I'm not sure where it came from, though I know that our host Dragon would be familiar with it seeing as how he clearly loves Anne McCaffry's books, where it is frequently used, but I don't think it was her invention. I use it a lot, and I probably got it from my dad.

Basically, it means bound to tradition or wary of new ideas. It's a reference to using animal hides as a material to write on, kind of a rougher version of Papyrus . Used to be very common, before paper was invented.
