As i'm sure you all are aware, most tone controls cut treble (in varying amounts).

Does anyone know how to cut mids or bass via a passive tone control? I would especially like to try a mid tone control.

Thanks heaps if any of you have any ideas

Paging Dr. Too.... Dr. ArtieToo, please report to the Sound room

I know thereamp;#180;s a way to cut the bass instead of the treble, but somehow combining low pass and high-pass filters to reach a quot;mid controlquot; is beyond my skills / state of awakeness.

Have a look around for Gamp;L diagrams - they have a treble control and a bass control instead of two tone controls - at least on some of them...

Definitely that way on my Legacy.

do you like it? Does the bass control come in handy?

I use the quot;treble bleedquot; caps on my neck pickups that go between the quot;inquot; and quot;outquot; lugs of your volume pot. Effectively, at full volume they're off, as you turn the guitar down via the guitars vol. pot, the output becomes less bassy. There's a bunch of different value caps you can use- I think the value I'm using now is .002 micro farhad.

The big plus is that it fights against your tone becoming muddy as you roll off your volume and really brightens your sound. The negative is that sometimes you have to compensate using your tone control.

There was a mod called the 'outlaws' mod back in the 70s- They played LPs but often needed a more tele sound and instead of spliting or rolling out coils, it notched the midrange down- All passive

For a bass cut, wire the pot and cap in series like an amp's resonance control; input to left lug (as you face the back of the pot), cap across left/ wiper lug, out from wiper lug. As the pot resistance goes up, the cap is paralleled into the circuit. For serious low end cut, you may need a big pot, like 1-5M.

For a mid cut, you need a high pass and a low pass. Check out AMZ's Big Muff presence control, which is usually here from : localhost/although it looks like his bandwidth is maxed at the moment. IIRC, it is very close to the BMP tone stack with the pot subbing in for the resistor to ground; he may have changed another parts value or two in there as well. You can tweak values with Duncan's Tone Stack Calculator, which is free from duncanamps.com

hmm... lots of basses have a full range (well, mid high low) eq. copy them?

or is that only possible with actives?

slade

None of my passive basses have tone controls beyond a basic tone pot.

My Gamp;L, which is active, does have seperate high/low knobs.

Gibson did mid controls a long time back (original Howard Roberts circa '74, and the varitone variants are based on the same idea), Torres sells mid kits, I'd rather someone buy from there than guitar-mod (ethical reasons, you can see my user notes in my profile). Steve Ahola also has a variation of the torres mid control on his site, complete with stock part numbers.
Also, Bill Lawrence's Q control is the same in *eq* mode. FWIW.
