When dealing with amps like the MG series, I think it's important to keep it in perspective: they are inexpensive, entry-level amps. For someone to expect that they are going to get the same tones from an MG series amp as they would a Silver Jubilee or Plexi is unrealistic.

It's kind of like the Line 6 Spider III's, Fender Frontman amps and a few others. They are good entry level amps that provide decent (but not overwhelming) tones and are often a starting point for alot of guitarists before they move on to something better.

Probably most of us started out with some "sub-par" solid state amp along the way somewhere, and as our playing got better, we got better gear.

I've seen some YouTube clips of guys playing through MG series amps and they made them sound pretty good.
