I have a Korean build Wollf 7-stringer. Though not boutique, still a fairly decent bass. Please note that I bought it when finance was low, and now being crisis-ridden unemployed, shopping a wonderthing is a nogo I need comments on two issues: 1. My B string lacks definition and sounds hollow. It's an Ernie Ball Power Slinky .135, sorta close to stainless steel alloy, which I feel could explain the hollow tone. Would this be a fair assumption? 2. I'm getting so juiced up on fretless that I'll want to convert it to fretless. However, reaching in-over the fairly wide board for the B-string is a bit to much for me, plus I guess the top plain F (fourth tuning) will likely serve mostly for pinching harmonics, but I could easily live with a top C. What to do? I could add a low F#, but I'm unsure how well a .185 or so would stack up on this instrument, and about it's usefulness for fretless. Earlier on I talked to Skib about his low strings for fretted use, but didn't get around to order, so.. I was thinking of stringing it up as a 6-stringer, B to C, and add an additional one octave higher B string next to the low B, i.e. as the seventh string, so I could play the low B stand-alone higher up the board, or hit both for a fuller, more defined low tone. Comments please?
