I went to my Fender dealer yesterday, and I saw that they had the Katana Mini, so I took a CV 60s Strat, plugged it in, and got instant Joe Walsh! This little thing sounds amazing, not for the size, not for the price, just plain amazing, with no qualifiers. It's the best practice amp I've ever owned of any size or cost. Unlike the Fly, it doesn't sound small, it sounds like a full sized amp. I can't believe the tone coming from this tiny plastic box that weighs about two pounds and has a tiny speaker. The clean channel set for low gain takes my overdrives pedals splendidly, they've never sounded better. Turn up the gain and it sounds like a cranked BF Fender. Switch to the crunch channel and with the gain at noon or below it's very similar to the clean channel dimed, with perhaps a bit more mids. Turn up the gain, and then it starts to growl more. I haven't even touched the tone controls, because it sounds perfect to me with them all at noon. The delay sounds just as good, with none of the digital artifacts that delay has with some modeling amps. Bear in mind though, it doesn't get very loud, even with the master all the way up, but that's fine with me, because that's what makes it perfect for me. It sounds perfect at the low levels that I play at to keep my tired ears, and my neighbors, happy. It's basically everything that the larger Kats are, just fuller sounding at lower volume. The Kat 50 had to be turned up to keep from sounding boxy, even on the .5 watt setting, and then it had a little edge to the highs that would make my ears start ringing after awhile. Not so here. The Mini also has the same great tube like feel and response as the larger Kats. The Boss design engineers should win the Nobel Prize for fun! Run do not walk, to your Boss dealer and pick up one of these before Roland realizes what they have and doubles the price, or (God Forbid), decides to "improve it", where the new version isn't as magic. As Ren and Stimpy say "Happy, Happy, Joy, Joy!", and I haven't even tried the Brown channel yet.
