I just got my 2nd (Replacement) JTV-89F from Sweetwater, the first one went back because L6 had installed a JTV59 board, and the modeling and tuning knobs were all wrong, misplaced I should say. It came up as a JTV59 on Workbench. Just got my new JTV-89F Replacement and I am noticing that the Low E string is barely audible compared to the other strings. And this is happening with and without modeling. After reading this string, I am not sure that the 89F is right for me if these issues are inherent with the Graphtec? Would I be better off sending back this 89F and getting a 59 hardtail? Thanks Guys!
