About the Marshall JCM900 4502:

The JCM900 4502 is the dual speaker combo version of the JCM900 4500 head. The single speaker combo version is the JCM900 4501.

Marshall have specialised in the production of valve amplification since 1962. The unique tone and playing response has formed the cornerstone of the Marshall “Sound of Rock”. The JCM 900 models split into two distinct product ranges, the Master Volume SL-X and the Dual Reverb. So although they share common ancestry their applications are very different.

Features of this amp.

Effects Loop Level Control: Adjusts the level of the effects loop from -10dBV to + 4dBm. Higher settings match modern effects processors and lower settings match floor pedals.

FX Send Socket: Jack socket for connection to the input of external effects processor.

Recording Compensated Line-Out Socket: Jack socket for direct connection to recording equipment or PA system. The signal is specially filtered for optimum recording performance.

Output Mode Switch: Switches the amplifier from high to low power output. The “low” setting configures the output stage to “triode” operation, which gives half the rated output (i.e. 25 Watts on 50 Watts models – or 50 Watts on 100 Watt models). The “high” power position gives “pentode” operation for the full rated output.
