I'm looking for a pedal which can give me the sound of an overdriven vox. I got a Vox AC15, which sounds just brilliant turned all the way up. The dirty, overdriven sound I get is just perfect. When I play at home I just use the top boost and the mastervolume to krank it. But I need something I can get this sound with live. When I play live I'm in need of more sounds than just the overdriven one. So, which pedal am I looking for?
