Continuing this Marshall quest, I fired up my ART Power Plant pre. I have always found this unit disappointing. I posted briefly about it years ago. There was a short in the tone stack and if it jumped just right, you got all this rich EVH rockin' tone. This time, having gotten a feel for the Marshall sound, I found the long lost magic setting and yes it's a setting not the short. Woot!11!!!!1 (wtf does that mean anyway?) Much joy this time around. Firing it up tomorrow for seconds.
