Reverb Tank - MOD®, 8DB2C1D, Medium Decay, 3-Spring

Question:
Will this tank work in a Marshall jcm900 combo ??

Answer:
From our limited research, the most common tank in the JCM900 is the 8DB3C1B. The 8DB2C1D is a similar tank with a medium decay, rather than a long decay, and a different mounting plane. We recommend the 8DB3C1B since it is designed to be mounted horizontally as opposed to vertically.
