Looking at buying a Chubster 55. I've also been looking at the Chubster 40 (hoping the 55 will have a little more headroom. There's also a Suprema 55, and a fifty-five twelve. i currently have a Fandango 100 2x12 and need something lighter. I can handle the Fandango, but don't want to, as well, sometimes it's hard to find room for it small stages. The confusing thing about Rivera amps, is that it seems that there isn't any real difference in the clean channel on most of these amps, with the exception of the Venus. This of course excludes the acoustic amps. Anyhow, wondering if anyone here knows more about these amps and can maybe tell me something that can clarify the differences on some of these amps in order to make an informed purchase. Yes, I've done a fair bit of reading on line. Also, if there are any Chubster users, I'd love to hear from them.
