My take on solid state Marshalls: Many were great, some not so much. I still like the MOSFET's (don't recall much about model numbers and names). I saw a KISS make-up tribute band at a bar WAY back in the 80's after KISS took the makeup off, and they sounded really good. The Paul Stanley/singer guy had a great guitar sound, so during a break I asked him what his amp was. He took me over and showed me his Marshall Artist head and cab. He told me he got it dirt cheap from a music store because nobody wanted solid state amps. He said this humbly as if he felt embarrassed because he couldn't afford a tube model. I told him he sounded really good and I think that made him feel better. The only early(er) Marshall SS I played was, as I recall, a Studio model? Whatever that was, I know the Peavey Bandit (tube) was more popular; it sounded great and had a lot more features. Moving into the 2K era, I really liked the early MGDFX series, not for live use, but for home practice. I had a couple/few MG15DFX's. They were the first solid state Marshall amp I ever had that could get you some killer tone with built-in FX for home rehearsal, learning guitar, jamming to tracks, etc. They were so cool - find the tone you want, then set it and forget it. You had reverb (spring? I forget) plus any choice of chorus, delay, flange. Like a dunbass restart, I sold them all at a garage sale for chump change during a time when I had other agendas in life. I'd pay $400 for a NIB one today, unopened and never touched by the humans.
