I was replacing a pot in my Cort bass when noticed it had a different tone control than I have seen before. Most tone controls have have a blank pot tab, but the blank one on this was wired to ground. I think when the pot is set for full tone the cap has no effect on the circuit. Most have upper freqs going to ground through the full value of the pot, and the low freq will be blocked by the cap. So a conventional tone control set for max treble will have 500k between the low freq and ground and 250k between the treble and ground. With the last leg of the tone pot going to ground on my setup then the cap is shorted to ground and both bass and treble have 250k between the signal and ground. So my set up would have a more flat sound at max tone with less volume. The conventional set up would have a slight treble roll off and more volume at max tone. Anyone seen this set up before? I searched but never found a circuit like my cort bass. I think I will wire it like most basses.
