This '06 Carvin LB-20 has the Hipshot A bridge, and I have strung it thru-body. Once. It was kind of a PITA, and didn't provide any aural improvement that I could hear. So, I never did it again. But, the Roto RS 775LD flats (it's strung BEAD) didn't seem to mind... The '78 Kramer 450B isn't
exactly a string-thru, but the effect on the strings is the same. And there's no option for stringing it any other way. So far, I've had no problems with it - and it's worn flats since I got it, about... oh, 15 years ago, now. I
will say that it's never worn La Bellas, though. But, not because of the string-thru thing. The "Old School" La Bella tone is just exactly
wrong for the Kramer. Even with the bright Optima "Chrome" flats it's wearing now, it sounds like an old P-Bass with La Bella Jamerson flats; a very, very
Loud old P-Bass....
So, I say - string that bass however you want to. They don't say
not to string those strings thru-body, so do it that way if you want. Personally, I think it's a waste of time, but... hey; it's
your bass;
your strings; and
your time...
