Marshall Jcm's

It appears taht all JCM 800's are not created equal. Althogh they have 22xx, some have Mk, some have other letters... Can anyone articulate on whats goin on? What is the best one? etc...

I own a few of these Marshalls. I can say that the JCM-800 2204 is a classic wonderfully harmonic Marshall. I does like all amps howeve have its shortcomings. My 50 watt does not clean up well at all. As a matter of fact, you would be hard pressed to even play with a driving drummer in practice and be heard. I would reccomend a JMP 50 watt over the JCM800. Cleans up better, point to point wiring vs. circuit board. Try and get a vintage 25 watt Marshall greenback 4-12 cab to go with it and you will have a pair that will never go down in value.

For what its worth
