    I've seen in a local music shop a 1979 Marshall combo with 2x12 speakers for sale. The chassis on back says it is a Master 50W MK2 Lead. I am not familiar with this amp and wanted to know whether it is considerd all tube and whether these are good, reliable amps. The amp sounded awsome and I wanted to make sure it isn't an early valvestate.

    I don't think Marshall started making their valvestate amps until the early 90's (93??, can't remember). Late 70's JMP master leads (2203 and 2204) are great amps-the combo must be a bitch to carry though!

    Valvestates came out in '91, but there were some sneaky Marshalls that came around with solid state preamps or diode clipping in the preamps in the late 70's and early 80's. My 2210 head has diodes in the boost channel of the preamp, but it ain't a bad thing. Saves me from having to run one more pedal on my pedal board to get some raunch out of an older corksniffer head.

    Buy that JMP! It's an amp you won't have any buyers remorse with!

    I've got one (1977) and its my favorite of all my Marshalls. Bought it, sold it and bought it back 3 years later. These amps just outright rock. I love the tones I get out of it with a P90 Les Paul. I think there's some magic in the original orange tolex too.:cool:

    Why does it matter if it sounds awesome?

    Many people would also argue ALL amps with solid state rectifiers are not "all tube".

    Just watch out for these crappy sounding SS combos.
    I gutted this one and turned it into a 1987/2204 hybrid.
