Thanks! Since the Ampeg SVT CL already failed on me more than one time, I'm looking for a backup amp in case the SVT goes again in assistance (more than one month...), even if I'll hope to solve the problem with a stabilized power strip/filters or whatsoever. I'm very happy with the GK but I think that goes in a different way. When @Wicked G told me about Orange in another thread (thanks!) I'm thinking about selling the GK for the TB or OB1, since they seems more deep, round bass/dark oriented than the GK.
Thanks again
I like the portability of the TB and the analog sound of the OB. Both take pedals very well. Both are great amps!
