Fair dinkum.
I'd say that an 800 (the 2203 in particular) is one of the quintessential 80's metal amps but I think you might need a little something to really get the juice out of it... even if that came in the form of a clean boost or an overdrive pedal, just something to get another 5-10% out of the pre-amp.

You could also try a BBE sonic maximiser in the FX loop
Makes a JCM800 sound crushing
Adds top and bottom and gets it a lot more Zakk Wylde like
Now, let's not get hasty.
I don't like Zakk Wylde's playing, nor do I like his tone very much - it's too thick and the bottom end is really loose. (Plus, if I wanted to drink myself into a stupor and hit pinch harmonics, I would've done that already :P)
A Marshall probably isn't the thing I'm looking for lead-wise, and it might not even be high enough gain for rhythm stuff. This is why I'm kinda hesitant on them. I'll make sure to check out the JCM800 as soon as I get the chance, but I didn't make a post recommending different setups for a Marshall - I'd like to avoid having to buy thousands of trinkets to get my amp to sound good. The only things I'd probably be willing to change are the tubes, and perhaps throw an attenuator in - that's already stretching my budget severely, though.
I think you may have misunderstood me a bit - I'd like an amp that
can do the hotrodded Marshall-type tones, but its main focus is a higher gain, tighter, more precise type sound.
Does anyone have any clips of that Engl rackhead? I can't find any on rocksolidamps.com.
