What's up! First time posting here. My JCM 2000 has been acting weird recently I have the reverb to 0 but its till giving me a ton of reverb....That being said im looking for another amp head one that maybe has a better sound for some metal/grunge. Any recommedations you could guve would be awesome. I already have an MT15 also I know alot of people love that head, but for me the gain when maxed is all feedback. Thanks
