Ungrounded tone stack

[passfan]

I just finished a Liverpool today and mistakingly left the ground off the mid control. I played it for a while without and I have to admit it was the cleanest crunchiest distortion I've ever had at my fingertips. I realized I had no tone control and located and corrected the problem with the expected gain and tone difference. I'm toying with the idea of putting it on a switch, possibly back panel.

That is a great option to have at your fingertips and/or foot switch! I love it and have been adding it to most of the amps that I have built lately.

Check in at the Dumble side of the forum as that (or similar) is standard fare on one (or more?) of those circuits.

Enjoy!

It seems that a pot with a push-pull type switch would be the easiest with the shortest wire runs.

Or use a DPDT switch in the Bright switch hole up for bright, center off and down tone stack bypass. Can't use both at same time without wiring it differently. But it would get brighter in bypass mode anyway.

Or use three way switching.

or just use a 250ka pot for the mid pot------for the the first half of the rotation you'll have your "25k" to play with in normal fashion and everything after that is just big ass boost. rh

Using a high value pot instead of a switch will also prevent the POP you will likely get from a switch at that location. I turn the volume down before I switch the amps that I have done something similar with.

you might be able to correct the "POP" with a 1M resistor to ground similar to how you would remedy an FX pedal from heavy switching noise.

Just a thought? I'd alligator clip it before I solder.
