First impressions.....not a bad amp. I noodled with the JM amp by itself for about half an hour before I A/B'd it with my other amps just to get a feel for what the amp is trying to do. With my favorite Strat and the tone controls at noon, the amp has kind of a Fendery neutral tonality but not what I'd call sterile. It just made my Strat sound about like what I think a Strat should sound like but without any odd coloration that I'd want to try and EQ out. The 1X12 cab is quite small, very light, and just large enough to enclose the lightweight Neodium (sp) speaker. I can easily pick up the speaker cab with one finger but it surprised me how full it sounded for its size. I then tweaked the tone controls for the best sound and, considering the small cab, the rig didn't sound too bad. The bottom end is deeper than my Roland Cube 60 and it has a nice feel to it....not too tight or too loose, sorta like a tube amp with a solid state rectifier. The digital effects are decent but you only have control over their depth and not their time....but there are a few time presets for each effect. You can also have delay & reverb simultaneously, chorus, vibrato, or a leslie simulation. There are also seperate FX controls & FX on/off footswitches for each channel. The OD channel sounds ok....neither raspy or mushy but I haven't played with that channel very much yet. However, it has a good OD range from just over the edge to approaching metal. To my ears, the OD channel sounds slightly more tubey than the clean channel. The amp is rated 250 watts so there's lots of clean headroom available for those who like that aspect. The clean channel can be very loud & clean....but with decent tone too. Compared to my Roland Cube 60, the Roland seems to have a low mid hump that I don't hear in the Fender, which is tonally more even to my ears. Don't know if it's a keeper yet but I definitely didn't reach for the packing tape after the first few notes. My first impression was that the Fender sounds better than the C60....but does it sound $600 better? Time will tell . More to follow....later!
