Recently I got a brand new Ibanez AM93 Lefty. It's an hollow body so I am using jazz guitar strings. I think I did a correct setup:
- Action is approx 1.8 mm in high E, and approx 1.9-2.0 at low E
- Neck adjusted, truss rod set up. Very minimal relief, pressing the 1st and 16th fret (neck/body junction) high E string has only a business card paper can slide and the string actually keeps the business card from falling down.
- Using flat wound jazz guitar strings, tried 3 different kind, all the same problem (string B is sharp).
- D'Addario ECG24 Chromes Flat Wound, Jazz Light, 11-50 (B is 15)
- D'Addario ECG25 Chromes Flat Wound, Light, 12-52 (B is 16)
- Thomastik GB112 Medium Light George Benson Custom Flatwound Guitar Strings (B is 16)
- Bridge is Ibanez ART1 adjustable fixed.
The action sounds a bit high (my Ibanez owner's manual recommends 1.5-1.8mm) but I can not lower the bridge more because it would be result fret buzz.
My main problem is that string 2nd (B) is still sharp but the bridge set up its longer long. If you examine the picture, high E and G also the longest, but in their case it is just in intonation.
Q1: What can cause that I must set my bridge for all strings so long and unfortunately for string B it is out of range?
Q2: I see that the adjustable piece is 180 degree reversed for the E, B, G strings than the D, A, E strings. As the profile of this piece (a wedge) is not symmetric, so rotating it for string B I got one more extra millimeter, which could be enough. The main questions are: Is it possible to rotate that piece or not? If it is possible, will it any drawback to sound of the B string?
(here is the pic, and note: it is a left handed guitar)
Thx in advance
