1979 Marshall JMP Combo - Is it all tube?

[Eugene Holley]

I 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.

It's all tube. I believe that is the combo version of the 2204. Great amp.

Valvestate Marshalls didn't show up until 1991, which is after the JCM 900 was released. A JMP is the real deal.

It is the combo version of a 1987 (2204 would be "MasterLead"... A cool thing about these top loaders is that the chassis can also go in a head shell.
