UPDATE: Oct 2012
RETIRED. This amp was satisfactory for many years when the only gigs I played were quiet jazz gigs. But soon as you compare the internal speaker with a beefier external speaker (same head), you can really hear what you’re missing (i.e. lots of frequencies and clarity). This shouldn’t be a surprise, as the internal speaker is squashed into the tiniest metal frame possible, with no ports or baffling. Go figure it sounds thin and metallic. But, hey, it’s light weight.
