All my heroes from the 70s had Marks. When I was 18, I had a Mark IIb - great clean amp, but didn't like that the drive and cleans shared the same eq. I should've ordered it with the EQ. I love that the MKV has 3 discrete channels.
JTM45 Many years ago I bought a new original 100w Silver Jubilee and hated it! Now I think what I hated about it was the speaker cab. I think maybe through greenbacks I might have liked it more. Even though I love the sound of a cranked JTM45 my ears won't permit that kind of behavior any more.
