I know Sunn manufactured at least two different looking versions of the concert bass amplifier, each had different specs. The question is, which version is mine? There are no markings that tell me what model it is! What troubles me is that for years I thought my concert bass amp was a 300watts @ 4 OHM model and would work with a 4 OHM cab, but when I plugged it into my peavey 1820 (rated at 200w @ 4 OHM) a few hours ago, it seemed radically underpowered.
