I play in a cover band doing all types of music. I'm always trying different amps and currently use a Mesa F-50 head. I love this amp but I'm not sure it exactly suits my band. I am thinking of trying one of the Marshall DSL 2000's. Is there any difference in tone between the 50 and 100 watt? I will be using in a 2x12 or 4x12 cab and it will be miced at most shows. I would lean towards the 50 because I don't think I need any more power than that. Anyone got advice?
