This will probably earn me eternal damnation, but I don't think that low B strings sound very good. A majority of the best bass players still play four-strings for that very reason, and when you do see a great player using a five or six-string, they just use the low B string as a thumbrest anyway. Go over to the talkbass forum and search "B string" or "five strings". At least a third of the posters are complaining about the tone of their B string, and asking what amp, strings, pickups, preamps etc. can fix it. Well, too bad - even a 35" scale doesn't address the fundamental mud problem caused by a too-thick string. It's the same problem seven-string guitarists run into, when you go over a .066" (or so) low string. You really can't have it all... If a five or six-stringer would please post a Youtube clip of someone specifically playing great-sound notes on a 0.135" string, I'd be proven wrong, huh? :laughing3:

(My new fave bass player is fretless six-banger Robertino Pagliari of OHM, but it seems he just uses the B as a thumbrest, as far as I can hear.)
