In order:
Played:
Mesa/Boogie Mark III half-stack that I bought in 1987 (can't remember if it was a blue stripe or red stripe)
A 1978 (I think) large box 50 watt Marshall JMP Master volume amp. This amp changed my life, before this it was all Boogie for me. It was an amp that was traded into the store I worked at and another guy that worked there got it. You could play a note and the bottom end of the note was clean and the top had this singing sustain, beautiful sound. I found one at a used mail order company, but when I received it, it had been modified with more gain. It sounded great, but it was not what I was looking for so I sent it back for a new 1987x (this was 1997ish). This amp sounded good as well.
1971 small box 50 watt non-master (model 1987) amp.
1965 Fender Pro Reverb amp (not my amp).
Trainwreck express clone (owned by an employer).
Marshall 1974 reissue (not my amp)
Mesa/Boogie Mark IIC+, wish I was able to keep it. I currently have a Mark IV, sounds good, but missing some mojo in the clean channel, for my taste anyway. Had to part with my Marshalls listed above (and the Mark III).
Heard:
It's hard to say about this because there are so many ways to interpret what you hear. I could list oodles of guitar player tones, but I might be wrong about what amp they are using at the time (i.e. Jimi didn't always play Marshall, he was American after all). However, there is a guy on you-tube that makes a lot of videos with his 1960 Bassman, 1959 Bandmaster, and 1964 Super Reverb that sound amazing. Also there are two Bludotone amp videos that make them interesting. One is the High Plains drifter (SSS Clone, Eric Johnson voicing), and another is a ODS clone. Last but not least are all of the videos of that guy that plays his Trainwreck Express and 1959 Les Paul.
I guess my taste is somewhat "normal". I like Fender style cleans, both tweed and blackface; a Marshall jacked up pretty loud controlling it with the guitar's volume and an OD; and Boogie singing sustain/crunchy rhythm sounds.
