DIY Tone Switch Warwick $$

[Mooks1881]

Hello! I did try searching but they may be too vague.

So anyways, I have a Warwick Corvette Double Buck and love it! The one thing it could use is a tone switch when the vol. is pulled out into "passive" mode. Because the treble knob only functions in active mode.

Has anyone tried this?

Is this a stupid idea?

And can anyone recommend any type of micro switch and cap/resistor raitngs?

Thanks!

Posted this in wrong forum, can this be moved to pickups & electronics?

You just want a switch that imitates the tone control on zero?

That's easy, you would wire up one end of the cap to ground, and the switch would switch the other end to the hot.

You can also get a center off switch. One side would be as above and the other could have a different value cap.

I'd suggest .047µF and .033µF. That would give you a deep cut and one that removes the top end and leaves the mids. You can also go up to .1µF and as small as .02µF for deeper and shallower cuts.

The cap values change the frequency the control works at, and not the amount. You can use a small 250K trim pot if you want to pre set the tone control half way for instance.

Very cool man! Thanks for the help! And I would wire this after volume before balance?

I've done this, well a luthier/tech did it for me. I think he used a .022 cap, but I had him use a 3-way switch.

1) Cap bypass
2) Tone "half way" down, adjustable by internal trimpot
3) tone all the way down. Trimpot bypassed.
