I'm using an Epiphone Les paul that is completely stock. I play anything from blues to shred to metal, and this amp easily covers them all. The clean channels on the lower gain side of the amp (Twin, Deluxe, Plexi, Brit, Bad Cat, and Classic) have pretty high headroom. Much better than (formerly) my VS30R. The Distortion is basically as high as you want it (Diezel, Krank, Recto, 505, JSX, and Triple XXX), or as low (the plexi is particularly good for hard rock and bordering-on-breakup blues rock).
Overall Impression — 9
I play anything, and this works fine. I own an Epiphone Les Paul Standard. I've been playing upwards of two years. I don't think there's anything I wished I asked. If it were stolen, I'd buy another and drop it on the thief's chest (it weighs about 30-35 lbs) then take my original back. I don't like the booting problems and the extra $125 or so you have to spend on it to make it perfect. I wish it had a better speaker, but they can be bought relatively cheaply. I compared it to a Spider 75, and this beat it out by a ton; spiders sound much more digital (because they use digital distortion) and don't have the processing power of the Vypyr, which I think has 2 32 bit floating point SHARC processors for the effects only.
Reliability & Durability — 8
The amp has not been updated yet to firmware version 1.53, so there are some booting-related problems. It has never simply cut out on me though. I can completely trust this amp for a gig... it's by far loud enough, and it easily gets over a drummer. There are no tubes to service because it is solid state (though there are two tube versions). With solid states, there really isn't too much to break down on short notice (except for the fuse).
Features — 10
The amp was most likely made this year (2008) in China. The amp has 12 models with 2 channels each, and yes it is very versatile. Blues to metal in the flick of a button. It has a USB recording out, but it is a USB B on the amp, instead of a "normal" USB A, so you'll need a special cable for recording. Updates are downloaded via MIDI which is another $30-40 dollars for a USB to MIDI cable. It doesn't need any effects pedals except for one of the sanpera foot controllers (1 and 2 are $80 and $180 respectively). It's got a blue marvel speaker, which isn't too great but is better than some speakers. It has 22 different effects (all editable) but a few of them are A) unusable without a Sanpera (the looper and pitch shifter, as well as the wah) or B) sound pretty bad (Octaver, MOG-which is a dual octaver, and the reverser). Most of the effects sound pretty good though, my favorites being the fuzz and the chorus effects.
