Marshall's MG30DFX is a well-built, great sounding amplifier. The amp has four built-in effects (reverb, delay, chorus, and flanger), and you can adjust how much of an effect they actually take. Also, many people say Marshall's aren't good for playing metal. I couldn't possibly disagree any more. I use this amp to play All That Remains, Children of Bodom, Lamb of God, Metallica, Cannibal Corpse, you know, some of the most metal bands possible, and it sounds amazing. The amp itself has a beautiful tone to it, either when playing clean or with distortion. The amp'll go pretty loud too - I'm sure if you turned it up enough, you'd get a call from some angry neighbors. You can also get a very wide variety of tones with the MG30. Personally, I use both bass and treble set max, and I'll vary the contour [I had never had contour on my old amps, not sure if it's uncommon, but basically it allows you to compress the sound more or less] per song. If you're playing with a lot of pinch harmonics, it really glorifies the harmonic sound if you set the contour to 10. The Marshall MG30DFX Amp: definitely look into this if you need a new amp.
