This amp is exactly what you'd guess from looking at it: A lower-price alternative to the Hartke Kickback 12. It's got the Kickback-style cabinet and the aluminum-cone driver. It's also got good tone and a clever "shape" control to adjust the tone. The "Dynamizer" input limiter helps give it a solid punch. Overall it seems well-built. The "Ultrabass" feature, basically like an octave pedal, is marginally-useful effect. I think there are other effects (chorus perhaps) that are used more frequently and would have been better to have on-board. Now for the bad news: I was quite happy with my new amp for a couple months, but it recently started having trouble. The power amp just fades away to nothing and the unit has to be powered off and on again to work. Too bad this happened after zZounds' 30-day return period because Behringer has an extremely limited service infrastructure in the USA. I will now have to ship this 50-pound item at my own cost to their service center and wait for about three weeks.
