The Mark IV was launched by Mesa/Boogie in 1990 as a three-channel amp - with independent controls for all three channels, except bass and mid, which are the same for both Rhythm 1 (clean) and Rhythm 2 (crunch). The "crunch" channel is designed for use by hard rock and heavy metal rhythm guitarists. There were two versions of this amp. Mark IVs built from the start of production until about September 1993 are referred to as version A; amplifiers made from late 1993 until the end of production in 2008 are known as version B. Early Bs have an attached power cord, like the A version. Some differences: Version A has no stereo effects loop or footswitch for reverb, and the lead channel is much like the Mark IIC+s. Version B has switchable reverb, a single switchable stereo effects loop, and an output to drive another power amp. Its voicings are altered slightly. Both versions are highly regarded; production of the Mark IV ceased in 2008 after an 18 year production run. This is the A version.

This one is in GREAT shape and sounds so full. Tubes were all replaced and biased. Comes with the FU3 footswitch.
