I am digging this Carvin 6 string with the Warwick preamp - the tone is killer. Here's a sample:
http://www.wikiloops.com/backingtrack-jam-54577.phpI am not too well practiced with a six string, but this bass is motivating me to learn it better. This jam was recorded in Garageband clean amp setting. I had the bass and treble boosted a little on the bass, and a little compression on the amp setting. The B string is so powerful on this bass, maybe a little too much (I think it needs a pickup height adjustment) but I am enjoying it.
