I have a brand new Custom Shop fretted P bass, which was playing very well with the stock strings (Fender 7250 .45-105). I prefer the sound of flats on a precision so I ordered a pair of Labella 760FL (43-104). The new strings play and feel great with a light touch all across the neck. However, if I just barely start to dig in on the D and G strings, I get that mwah buzz sound anywhere above the 7th fret up to the 16th. The relief looks to be about right after I did a truss adjustment of about 1/8 turn clockwise, leaving .012 (0.3mm)" of relief. The string heights also look bang on according to the Fender setup guide (2mm on the G and 2.4mm on the E). Seems I should leave the truss rod alone since the E and A strings work well. I couldn't seem to tighten it any further than this anyway and I don't want to force it. Is this something to be expected with Labellas? Anything I should try? Note also that raising the saddles didn't seem to help much! Thanks in advance!
