I just got a new set of La Bella "Deep Talkin'" 760LM (Medium Flats) strings for a 6-string for my Ibanez SR496. The bridge is not "through the body", but is a really cheezy plastic/metal allow. Got 'em on (tension wasn't as bad as I feared), but I can't get the low-B to intonate! The 12th-fret harmonic on the "B" string sounds almost like a "C", per my tuner; at any rate, quite sharp. I lengthed the string at the bridge, even removing the spring in the bridge for that string so I could move it further back (lengthen the string more). The string is "tapered" (less windings near the bridge), and I've lengthened it so far I'm getting past the "messy" windings near the ball at the end of the string (the messy windings are touching the bridge)! My TI Jazz flats had a bit of an intonation problem, but nothing like this! The rest of the strings intonate fine.
