New to me SV20H that I just picked up today. Not my first Marshall. I had a Lead 12 combo in the 90s, and a DSL5CR not so long ago, which I did like even with a Greenback. Tried a British Vintage 12 from Carl’s Custom Amps that didn’t quite nail the Plexi feel and sound. First impression is WOW, why didn’t I get one sooner! Even with the Mini-Mass that krrrang is there, easy to dial in AC/DC tones. The responsiveness to pick attack is fantastic and how it cleans up with the volume knob without losing treble. The clean tone is also great. Sometimes there is no substitute for the real thing!
