A mighty beast

This amp prove that not only bass amp can produce enough energy to make you shake from the inside. This amp was made in the mid to late 1970 and was part of the handfull of amp that defined the 70 and the 80. This model is part of the second generation of marshall amp. The first generation being the classic ''plexi'' amp (JTM,1959 and 1987X). The JMP where the firsts models to have a Master Volume and a Pre-amp volume (gain). They sound really similar to the previous line but with more gain on tap. The JMP line became the JCM line in the 80 with the first flagship being the JCM800. Some say that the only difference between the JMP and the JCM where the changes made to the face of the amp. While the Master volume give you the ability to play quieter, the amp really is at his best while cranked to get that stressed el34 grind that we all have learn to love. To be in a room with this beast of an amp cranked into a 4x12 is an experience that everyone should feel at least once in his lifetime (with earplug of course). This is addictive and you'll always want to play a little more. A good complement for this amp is an attenuator.
