So I read someones post where they were talking about letting their amp warm up before playing and I thought it was placebo. Or just someones ears adjusting to the tone over time. I was wrong. Boy was I wrong. I let my MarK V warm up for about an hour on standby and then turned it on with the mute engaged and when I played on it I swear it had more gain, sounded tighter and hotter. Thanks to whoever pointed that out.
