Any opinions on these? Recently, I've come across one of their HD One-Sixty models for a pretty decent price. According to the rear panel specs., it appears to be rated at 300 watts. The chassis seems pretty small, though. (Not that this should really elude to a lower power rating.) I'm left wondering. Anyone out there have any experience with these amps? What is the "vintage-factor" sound-wise? Also, what are your opinions on MusicMan cabinets? In particular the 1x15 and 1x18 models? Thanks in advance.
