JCM900
Marshall's 1990s gain-forward head, the successor to the JCM800.
Why it matters
Introduced in 1990 and still current, it is the gain-forward model in the line, after the JCM800 and before the four-channel JVM410H. Players who want more gain on tap than the master-volume design start here.
Note
The 90s gain-forward successor.
