Getting rid of or simplifying control on a bass/guitar

I noticed that Jay Bentley of Bad Religion modifies his basses to have no control (Lol) knobs. I would like to how to do this because I don't mess with my tone or my volume at all.

Some can be unscrewed and popped off. Others can just be popped off. Will be tight if never done before.

you may not be messing with your tone and volume but your tone and volume are messing with you.... removing those pots and the tone cap will change your treble response and output as even at 10 they are introducing resistance to your pickups.... but if you want to go for the bad religion it can be done, the wiring changes will vary a smidge based on where your tone and volume are in relation to your pickup selector (if you have a pickup selector that is). You will basically desolder the pots and replace them with straight wires to the pickup seletor or jack. Should take longer to heat up your iron than to do the work.

Lots of people have tried this mod, most put the pots back in, at least the volume pot.

Other artists do this to, I know Yngwie Malmsteen would take the volume pot out of his Strat and Jerry Only has no controls in his custom bass.

Edit: Eddie Van Halen also removed the volume control on his custom guitars like The '78, The Bumblebee and the Frankenstrat.

neil young's old black has a switch to send a straight wire past the volume and tone pots for example... a stock fender esquire bypasses the tone pot on the 3rd switch position.
