Hi! I've purchased a "telebration" Cabronita and would like to install a TONE control. As you folks know, Cabronitas only have one control - VOLUME. Even though my Cabronita is not an original edition, but a "telebration" re-edition, I want to go ahead, as I use to control the higs from the guitar, instead of using the amp or an equalizer to do so. It seems to me that the most non-intrusive way to get what I want is using a concentric (stagged?) VOLUME - TONE pot/knob for the job. Are there pots that would let me do it? Thanks.
