Hi Tony , couple of clips here, just a field recorder but it gives the flavour. first is plexi mode master & pre amp vols all at about midnight. second is 800 mode with master a 3 oclock and pre amps as before. this means the volume in both cases is about the same.(loud pub gig). first bright switch to the right. very tweakable amp giving pretty much any marshall tone except uber gain. it's a 50w. guitar tokai lp with bridge vh11 engaged.
