To me, this amp is a must for death metal, I have never heard an amp that can put up so well with low frequencies.
It's incredible. I tune to A, with 13/64 strings, and have no muddle, no trembling speakers, nothing, it behaves impeccable.
In terms of distortion, I use the OD2 channel, which is really mind-blowing. It's powerful and relatively light at the same time.
I use Seymour SH-6 SH-8 X2N at the neck and don't have the slightest need to connect a single pedal to have a additional gain.
To give you an idea, when I connect a Metal Muff, I can hear no gain difference whatsoever, except for some extra gain in the high end.
Do note that, like with many Marshalls, the mids and treble controls aren't as good as the bass one.
The pots crackle when you turn them, but that's quite normal for a Marshall.


I've been using it for about 3 years and I had several amps before, including a peavey bandit 112 and a marshall amphead with an 8100 cab.
The bandit 112's speaker vibrates at loud volumes with a standard gauge and the 8100 lacks punch, I had to play with a pedal, but I used EMG 81 and 85 with this amp, it was way less powerful than with the SH8, which may skew my judgment.
I love its punch and its particularly metal sound. The amp responds perfectly to low frequencies and thick string gauges (I use 13/64).
What annoys me a bit is that the reverb sets off at 10 on mine.
I have never really cranked the volume all the way up. The most "extreme" settings I've used have been with both the boost and the master volume at 4, and it already kicks ass.
Then again, it's only 80 watts, so it's not the best to play with a band.
It maybe okay to play soft music, but to play death metal you'll need at least twice that to be heard over a drummer who plays like a real death metal drummer.

Metalheads should go for it, you won't find anything better for the price.
I would eventually like to compare it with a LINE 6 Spider, but I don't think its speakers are of such good quality, even if I know that the latter has a more modern and cleaner distortion than the Marshall.

Do note that my reverb only works when set to 10, which means it sets off at full throttle at 10.
