I usually play guitar but fill in when our bass player is out (contemporary Christian music). My old amp died on me (second time: no replacement parts) and I checked out this and it's bigger brother KB-15. I like the light weight, and it's a very tight low end but can warm nicely too: quite versatile. I use the other bassists' 70's Ampeg SVT 8-10 beast (!!!) when I fill in so I'm a bit spoiled. I'm going to side by side them some time and look forward to comparing them. I would much rather transport this loud little guy than and SVT.
