the one that starts with "A" and ends with "mpeg"
Check the sig, most winningest combo ever (would be more winning if i swapped the 3pro for a SVT..., but winning enough)
But it really depends on the bass, i think. I've heard some active basses (like my cort for example) that really don't sound as good as passives through my system. I think Ampeg is awesome for Passive stuff only, and ok for active stuff. One thing though, my rig was the backline for a school show, and someone had a G&L ASAT and it sounded AWESOME. Rickenbackers and Fenders sound awesome through my rig. If i were ever to get a real SVT, it wouldn't be one of these crappy cratepeg's their selling now, it would be pre 80's for me. Although, my bass instructor has a sweet B-25 (55W all tube) that sounds AWESOME, and hes running it through craptastic 10" monitors (just for our lessons). but he has an 8x10 for when its needed, but the sound of that thing is awesome!
