    I'm planning on installing a varitone with 5 caps and a bypass in my Epi EB3 and I can't seem to find a rotary switch that'll go through any of the pot holes to a point where I can put a nut on it. Other than removing some wood from the control cavity, does anyone know of a rotary switch with longer threads or a way to extend them?

    I think the tallest threaded shafts are 3/8".

    I once installed a rotary switch in a Les Paul once. Because it had the aluminum box inside, I got a switch with a very long shaft, and attached the threaded part to the box. Then I got part of an old pot to use for a bushing on the top.

    For basses I've had to rout that part a little thinner.

    Or buy a Forstner bit the diameter of the device. But use it on a drill press or make some sort of limiter so you don't bore all the way through your bass.

    You have to watch some Forstner bits too. The larger ones have saw like teeth around the outside edge.

    I prefer to use routers for this kind of stuff. But Forstner bits are handy to have to. I'm just a router kind of guy. ;)

    I get freaked out by the über high speed of my router.

    Yeah, they are scary, but that keeps you on your toes.

    Try using a jointer. That's a scary machine. I still have all my fingers. :)

    I found that a metal-bodied Alpha rotary switch had enough threads to go thru the top. I was going to use a plastic-bodied Alpha switch initially which didn't have a long enough bushing. So, problem solved and EB3 is all wired up and fun to play!
