Raven Rg100. or a Peavey Valve King 112. to get a good metallica sound
You wouldn't need a pedal to get a Metallica tone out of the VK. I brought my Metal Muff into the store and tested that on the clean channel of the VK, and then tried out the OD channel w/o the pedal, not much difference.
yes but I have a metal muff and I want still want to be able to use it with my new amp
try for yourself. tone is subjetive
Valveking would probably be better, you wouldn't really need the Metal Muff then. The Metal Muff isn't very good though, but if you like it then whatever.
ive got a good metallica tone with it right now. My amp just is crap and hisses
Well if you like the distortion sound you're getting then I'd suggest getting an amp geared more toward cleans. And just use the pedal as you please. I think the onboard distortion on the VK is better IMO though, but hey it's your ear.
