26 Proteus 1 month ago Haven't played through a Katana in person, so I can't comment. It was, however, the top selling amp on Reverb last year, and the negative comment above is the first I can recall. Given the price, and what you get for that money (whether or not you're an avid effector), I wouldn't buy a solid state amp now without trying one in person.I know most of the other candidates which have been mentioned. The Quilters, from the 45-watt micros through the heads and combos, are to my ear The Standard. They seem to do everything well. But they're comparatively pricey, especially in comparison to the dominant Katana. If you don't mind spending Quilter money, I think the search is over.BigJim mentions the Hotone Nano series. I have three of the little 5-watters (British Invasion voxbox, Purple Wind marshallike, and Mojo Diamond fenderite. They all do a remarkable job of capturing the tonal profiles they're after, and are louder than you think. And I have two of the Nano Floor Series, one which combines the Brit Invasion and Purple Wind, another combines the Mojo Diamond and their full-shred Boogie emulator. They're rated at 75 solid state watts, with reverb, easy switching between the voices, and...some other useful feature I can't recall. Effects loop, maybe? I really like them.But with any of them (or a Quilter micro or head), you need a cabinet. Personally, I like going that way rather than a dedicated combo, because it's easy to mix and match for the occasion. I get all the variety without all the cabinetry. (I have a Cave Creek/Powdog cab with a Neodymium speaker which weighs in at 18 lbs.)The little 5-watt Nanos are like party favors or Christmas ornaments, and not much more expensive (generally 75.00 - 100.00 used). The Nano floors, with the double-amp voicing...are more like 175.00 - 200.00 each. By comparison to a Katana, they're expensive for what you get.So...the first thing to do is try a Katana. If you like it, done. If not, start shopping upward.I'm very impressed with the Tone Masters. I've heard the Deluxe for many hours, in jam/gig conditions, with Fender tube amps to compare them to - and honestly liked the sound of the Tone Master better. It nails the intended identity, in that the difference between a DRRI (or a vintage DR) and the Tone Master is no more than the difference between two examples of either of the tube versions. Except it sounds like the most expertly maintained and tweaked tube DR I've heard.But. Expensive by comparison with other options.I've had a Tech21 Trademark 60 for years, and - before the Quilters - considered it the best SS amp I'd run across. It's tone and gain controls are unlike most other amps, and take some getting used to - but it does a fine job of sounding Fendery, or Voxy, or Marshally, or what have you. Not that it's trying to model or emulate - just that it gets in those tonal ballparks. And I love its dirt options. It's also very light, and real loud (and has the lousiest thin fragile this-sure-ain't-tolex black skin I've ever seen, so treat it with care). I still use mine, as I have no need for an amp which would justify selling it to get a Quilter.Thing is, even used, the Trademark 60 probably costs as much as new Katana.So there you are. From my knowledge of the state of that art, at the higher end it's a choice between a Quilter (if you want gobs of versatility) or a Tone Master (if you want Fender blackface period). At the affordable end of the scale, it's Katana. Various mini-head-and-separate-cab options fall between those endpoints.As I said...before I spent money on an SS amp today, I'd have to eliminate the Katana before I considered other options. Oh. Blues Cubes. I'm impressed by proxy by what guys whose ear I respect have said about at least the top of that line (but haven't heard the amps in person). They're pricier than the Katana. I suppose I'd audition one vs Quilter and Tone Master in that price range.
