I played one of these in a studio we rehearsed in a week ago. It was one of the old tweed style models w/2x12" speakers. It was totally beat to hell and in horrible shape but it sounded great. Nice clean sound, great midrange, no spikey highs with decent reverb and a great pedal platform. Definitely a nice EL84 sound. I see the new models look much different. If this difference only cosmetic or have they changed the quality/sound any?
