I'm a thumbpicker who's used to playing as a single act with a set of 12's, using both pickups and a lot of bass. The guitar is a standard Tele from the early 90's. The amp is a MusicMan 112. I've recently joined a band playing traditional country (1950's and 1960's) and I'd like a clean twangy sound that's a lot brighter than I'm used to. I've tried just rolling on more treble but that just seems to get harsh and brittle. Any recommendations of strings, pickups, amp setting, or pedals I should use?
