General Comments
I play all sorts of styles of music and I never consider myself a slave to one brand of amp, guitar, or effect unit. When I need that signature crunch at any level of volume and distortion I can always count on Marshall. They invented the sound (with a tiny bit of help from the modified Fender Bassman circuit).
I have been a musician all my life, and grew up in a musical family. We all play and studied music formally. I have been playing guitar for nearly 30 years. I own several British-made Vox AC30s, Marshal cabs, Line 6 effects, Eventide, Ensoniq, tc Electronic. I use some MXR, Ibanez, BOSS, Roland effetcs and Ernie Ball pedals along with a Bradshaw switching system and a Sound Sculpture Switchblade.
I would replace this unit in a heartbeat. So many of the sounds people hear from guitars are generated by the Marshall preamp. And it just sounds great anyway. There is nothing about the unit I do not like. I like the ability to bring MIDI into the equation. I have owned Marshall heads and its nice to be able to recal a wide range of different sounds from the push of a button, and also because it is a tube unit. You cannot beat tubes for guitar. Tubes add a character and warmth you can't easily find in a tone of solid-state units.
It helps me make music in the way most of the gear i have does, itcan generate a wide enough array of "colors" that I can come up with something I feel fits into a particular piece of music.
