Good Rockin' Amp
I finally got a chance to get this amp in a nice loud band situation. 2 guitarist, each using a 2x12 combo playing classic rock. For lightweight and high volume this amp definitely makes the grade, even with a 5 string it has strong tight lows. Being a sealed cabinet it has a bit of SVT flavor you can't get with a ported cab and at 49 lbs it's easy to move. The overall tone is fairly natural with a slight mid-range bump. So it is not HI-FI sounding like some brands but will cut through guitars just fine. YMMV but here are my complaints considering this is not a terribly inexpensive amp. It lacks pre-amp out and power-amp in connections, an extension speaker connection, an effects loop or a tuner out. I personally don't use effects loops or tuner outs, most combos these days run at 4-ohms and don't have an extension speaker option(annoying trend) but I really would like line-level pre-amp and power-amp connections at this price point. There are times when I just prefer to use a different pre-amp such as a tech21 BDDI. I did not find the boost, limiter, or contour switches to be useful to me. If you like the GK sound and don't mind being a little hemmed-in on expansion options, because you'll almost have to buy one of their powered extension cabs for a matching bottom (or buy an A/B box / splitter and run a 2nd amp), then it is a really good amp. For some folks/situations it will be perfect amp. Classic and old school hard rockers will love it.
Full Disclosure: I purchased a demo model at a significantly reduced price. I am not sure I would pay the full new price for this amp with the aforementioned shortcomings. I am satisfied with my purchase though and as always Sweetwater's service is second to none.
