I brought out my SB5k to a gig last night for the first time and it sounded great doing top 40, R&B, etc. It rocked! I have to say, I was sort of on the fence with this bass in that, much like what the J bass peeps say here, it always sounds great when practicing alone at home but I have a hard time dialing it in and getting it to cut through at rehearsal with a 6 piece band in small spaces. I never thought of ever selling it but I figured it was just destined to be a good looking practice bass. Well, last night I bumped up the mid lows and dialed back the low lows and it sounded monstrous in a 60 person club. There were some sound guys in the audience (one of which plays bass) and they both said my sound was outstanding. I even got a little P-bassey sound going on with the front pickup soloed and a little EQing. I am 100% sold on this bass and I plan on putting a lot of miles on it!
FYI - I was going through an old school rig. Ashdown ABM 500 G1 and...dare I say it here on TB....An Eden 2x10 and 1x15 stack. Hey, I like matched cabs like everyone else but this is all I got for now and it still sounds good!
