Hey guys, Im looking into getting some nylon wrapped strings for my Lightwave Saber VL 5 string fretless. ive never had nylon wraps before, but from the general description, i think ill like them. the three in particular im looking into are the Rotosound Tru Bass, the GHS 3060, and the LaBella 760N-B, and wanted to know which would be the best to achieve a warm, upright sound with. Right now, im leaning towards getting the Rotosound Tru Bass strings. One thing concerns me though. i recently put some D'Addarrio flatwounds on my bass since the folks at lightwave for some reason shipped round wounds on a fretless bass, and found that while the .135 B string fit through the pickup/nut slot, the wrapping at the base near the nut did not. i ended up having to shave off some of the string wrapping to make the string fit. the rotosounds have a .135 gauge b string which the mfg tells me is closer to .138 after they add the nylon wrapping, and im concerned this wont fit, while the labellas and the ghs are .128 and .125 respectively. im not completely against modifying the nut slot, but the close proximity to the optical pickups (they are part of the same assembly) gives me pause to do any of this kind of modification. and honestly, ive done some searching, so if they exist i cant find them, but why dont manufacturers make any coated flatwounds. seems to me these would be ideal for fretless bases.
