How are these? My school owns one and I've used it before and sounds really great. But has anyone ever had bad experiences with them? and what was the loudest you've turned it up to? what about a low B on it? Compare it to a b120 120 watt combo amp with the 2 12's (because that's what I own). The one at school is pretty beat up with a bad power input (loses power contact when you "kick back"). Despite its abuse, it's got a solid sound. I just want to hear your reviews, and comparisons to my b120. How loud does it get and when does it start to bottom out if it does? Unfortunately I cant just plug my bass in and check how loud it gets at school jazz band ... Just wanna hear your comments complaints... I've been checking Harmony Central's reviews on this. Would it be wiser to get the hartke 3500 or 2000 with an avatar 15? or would this kickback compare well? I've played through these atSamash and love them, and it gives a really thick tone in jazz band that I dig. I'm not the electric bassist for my school's jazz band, I play upright for school, but Im mainly an electrician Lemme hear your stories. Plus it's in my price range... I could probably use my 2x12 as a back-up. The 2x12 is bulkier but lighter by alot, and plus a 15 handles a low B better, and with the aluminum cone on this thing, I don't think a tweeter/horn is nesecary for defintion.
