About a week ago I put a set of Fender 9050ML flatwound, gauges 50-100 on my Rickenbacker 4003. They sound ,much better then the Ernie-Ball flats I used to have (just couldn't stand the dead "E"). The problem is the V E R Y high tension the Fender have. I think the neck got a little bow, the action is a bit high for me, and when I low it, I get that buzz on the higher frets (problem I never had with my previous sets of strings). Do you think a set up would solve it, or should I try a nother string brand? Thanks guys.
