I love my Ampeg PF-500 but for bedroom practice I really wanted to like the BA combo amps. I bought a BA-112 and after a day I could hear a rattle sound even at very low volumes so I returned it. I then decided I will just get the BA-108. It came in yesterday and it rattled even worse than the BA-112 even with the volume on 4. I decided to unscrew the amp portion to see if it's rattling against the cab. I took it out and put a shirt against it and the cab so it wouldn't rattle. The rattle completely went away. I added all kinds or foam tape all around the amp chassis and installed it back again. The rattle was still there. I took it out again and tried some more but I could not get rid of the rattle. Anyways I returned it today and can't decide if I should try again with another one or just get something else like a Fender Rumble 15. BTW other then the rattle the tone was really good.
