Help! I am planning my controls for my next build, and am thinking I'd really like to have flush mounted volume & tone controls, similar to the tone controls on the upper horn of a Fender Jaguar bass. Problem is, I don't have the slightest idea of what those things are called, (Fender calls them "inset control wheels", but a search on Google turned up nothing) or if they are dependable/robust enough to use as my main vol & tone controls. Or..., where to get them. Anybody got some hints, clues or outright help for me?
