Who here owns or has played the Rockerverb 50? I'm very curious about this amp. I know it has 4 6v6's. I'm very much used to using EL84 30 watt amps into 2x12 cabs. Will I be able to get that big 3D open sound on the clean channel of the Rockerverb 50? How does that amp compare to something like a /13 FTR-37? Any thoughts on this amp would be great. I've been looking around trying to find one for sale, so if you know of any good places to call, let me know that too.
