I did check it out with the extension cab and thought it sounded great, but I'll wait for a used one to show up.. I'd like to check out the 15" version, but they didn't have one in stock.. This little rig may be fine for most of the country club and nightclub gigs with some P.A. support.. I got the amp for a great price so decided to snap it up... I actually hate the color scheme, but the little bugger sounds good... I have a Mesa M-3 combo which is fantastic, but getting too heavy to load in and out of my truck... And I also did a nightclub gig a few weeks ago with my 25 watt Crate little practice amp which was fine for that night, but not most others.. I was trying to blow the damn think up for 2h!t2 and giggles, but it made it through the night unscathed... I also have to see if this amp can handle effects such as an Octaver...
