Over the years Ive probably had at least 30 different old Marshalls, 68-79 mostly. My first was a 72 50 watt that blew up all the time. Back then there really were not many amps to even choose.
Playing them at 4 hour gigs were tough, the last set and a half they were always just a mud fest. Also the ghost notes were terrible and to run any FX took a ton of gear. But for that middle set and a half they sounded great. Some nites would be awesome tone, some so/so and some terrible.
Still have a 68, two 69’s, a 1959RR and a 74 Hiwatt DR103. I play them at home for recording from time to time but the Wizard goes to every gig. With the Wizard everytime I turn it on, it sounds the same. Rarely ever even have to adjust a knob from room to room. There are other amps I like alot too, but perfectly content with this Wizard.
But no amp is for everyone. And at $5200, man that is just too much for any amp. But in my mind an early Marshall is still a $350.00 amp.
