Bass cut

[razar]

Does anybody have working passive schematic suggestions for making a bass cut with the Tone knob instead of commonly used trebble cut? I think that could be useful for playing funky rythmic stuff, maybe with wah, and switching to normal full-toned pickup sound when needed. I've made a simple external schematic to try this with 2.2 Meg pot, 470 pF capacitor and a 220 K resistor, it works, but i'm not satisfied with the resulting tone.

Re: Bass cut

You could go to the G&L website and look at some of their schematics some of their guitars have both treble and bass cut controls.

And this thread from a few days ago was about doing both with a single control.

Re: Bass cut

Check the schematic for the Ibanez version of the Howard Roberts...a 'bass cut' circuit without a choke (vs the Gibson HR or Varitone circuit w/ choke).

I would love too. Can you tell me the model number for the Ibanez version of the Howard Roberts from this list?

If I am not mistaken, the Gibson version of the Howard Roberts did not have a bass cut control. It was a midrange cut control and that needed the choke. Varitones are just different frequency midrange cuts that are selected by a multiple position switch.

you could try a parallel or out-of-phase system? these cut a lot of bass out, it's what makes jaguars and mustangs so good for surf

I agree about the Mustang. Their switches allowed both pickups to be combined in and out of phase.

The Jaguar did not have a phase switch. It had a switch on that plate of three slide switches that could be activated at any time to place a .003 cap into the circuit to cut the bass no matter what pickup combination was activated. This of course only pertained to the lead circuit and not the rhythm.

Both did combine pickups in parallel though but this combination seems to cut midrange instead of bass.

Both were so good for surf!!

Re: Bass cut

that's interesting info, i assumed the mustang and jag switches did the same thing

you could always try an EQ pedal?

LOL---doesn't go back far enough, the Ibanez HR was probably early 80's. The schematic is reproduced in the Brosnac book on guitar electronics. Anyway, the Ibanez functions more like a bass cut. Ummm, Varitones sure did have a single 1.5 Henry choke and five caps ranging from .001 to .22 mF (cap values depend on year, model, mono/stereo, etc).

Re: Bass cut

Thanks for advice! Anyway, it seems to me that all working ideas about making bass cutting tone control in guitar are very close to mine All i have to do is experiment - if i succeed i'm going to write about it here.

About out of phase sound - i already heard this type of sound when i made a mistake in wiring But for realizing this idea i need extra switches, that does not seem attractive to me, and this sound is not quite that i want. Using EQ - yeah, thats easy. Besides it is possible to make this right in my tube preamp, i think about it.
