Did someone call me?
No, seriously: I've had my Kickback 15 for about one and a half years now. Bought it used, it has paid itself off on the first weekend of gigging.
- very bright for a 15
- thanks to the Kickback design and the aforementioned point, I'm able to hear myself very well in every situation.
- works well with upright. The shape function is more or less a notch filter which can really be a life saver
- very loud for it's size
- great value if bought used
- able to carry a bar gig with a bit of PA reinforcement (maybe without if the band isn't too loud)
- heavy for it's size
- awkward to carry with the single strap on top
- not much deep low end. I haven't measured it (yet), but there can't be much happening below 80hz. Most combos have that problem, though. Can be an upside when used with upright, though - less feedback problems.
- very Hi-Fi sounding, not much character to it, but works well with pedals. So I use a preamp (VT Bass or Zoom B3) when playing electric and all is well.
- dispersion could be better (it's a 15, duh!)
The downsides really aren't that big a deal to me. I've yet to find something that works as well or better in such a small package.
In short: it's a great workhorse amp.
