I've been offered a StingRay from a guy (appears to be in great condition, black body, black pickguard, maple fretboard) for $500. Problem is, it's a lefty. Now, I could flip the nut around, do some set-up work, and re-string it righty, but do you think the knobs would get in the way? I play with all different techniques, but mostly with my fingers. Could I maybe install knobs like I've seen on guitar pedals that are recessed until you pull them out? (ie, Ibanez PH7) Help & Suggestions appreciated. Thanks, TB!
