Funny you mention that -- the GC near me actually had those in stock! I'd never heard of them before so I passed. Anyone tried them?
They're a black nylon taped string. Supposed to give a real nice thump on P's, not to mention they'd look sick on my bass.
The only posts I can find here at TB are pretty vague, but all say they "give more thump and thud", "sounds almost like an upright or fretless" and "no string noise or fret buzzing". I did find one post here that mentioned the guy had a problem with them and they caused his bass to buzz / hum horribly. But this is surely a ground issue. I'm eager to get my hands on some. Not sure what they would sound like on a J though.
