Over the last years or so we've had a few "best metal amp" threads & I always post my recommendations based on amps I've owned/tried. Well I have one to add to the list:
Marshall 2203KK (the Kerry King sig model)
Tried one yesterday - haven't heard overdrive this good from a Marshall since the JCM900 SL-X, maybe ever. Really heavy, thick, yet clear overdrive with tight punchy bass. I've posted before about how much I like 6550/KT88 power valves & again I find the same advantage with this amp as with my Engl Savage & the wonderful VHT Ultralead - the power section is very "clean" & reproduces the same great tone at almost any volume, unlike most EL34-driven amps I've used which seem to need to be wound up before they come alive (6L6s seem to be somewhere in between). Anyway, I liked this amp's sound a lot - it may lack features (no FX loop is a big disadvantage IMHO) & have bugger-all versatility, but if it's metal distortion ONLY that you want, check the 2203KK out...
In summary:
Pros:
Plenty of gain/punch/power/depth - great metal tone
Noise gate
Sounds really good even at VERY low volumes
Price <£1K (seen for as low as £740)
Cons:
No FX loop :(
Single channel
No footswitch for the boost
No, I didn't walk out of the shop with it - this isn't a "NAD" thread, though it was close :)
