This amplifier was voiced with a more mellow lead and crunch modes, with slightly reduced gain. This is an estimate of the production year for that amplifier. This is the estimated number of years the amp was made after the Mark was introduced.

Much like its close cousin

Examples of this amp in its original form and in good condition are sought after by collectors and guitar aficionados. Much like its close cousin, the Triaxis Preamp, it features many voicings based on previous Mark Series amplifiers. It is a smaller, two-channel version of the Mark V. Reverb was optional, and not present on many early Boogies. It has three distinct channels, each with their own pre-gain three band tone stack, gain, master, and presence controls.

Version B has switchable reverb, a single switchable stereo effects loop, and an output to drive another power amp. Early Bs have an attached power cord, like the A version. It is difficult to date those models anymore accurately than sometime within the range. Channel-specific Multi-Watt toggles dictate the power amplifier's operation class. Older Boogies were equipped with graphic equalizers, but these did not allow the same flexibility.

The new footswitching system relied on a relay, which made an audible popping noise when switching modes. There were two versions of this amp. It is also available as a combo and a head.

In addition, Mesa Boogie makes a large number of special orders for amplifiers, so the presence or exclusion of features is not an indication of the production year. The reverb modification involved resistor swaps and a change in ground lead placement. Furthermore, the pull function labels above the Bass and Middle knobs were hand-etched onto the face plate resulting in a slightly different look than the other labels on the faceplate. Anderson majored in chemical engineering and has training in guitar performance, music theory and song composition.

Additional solo controls were added for independent volume switching. Its voicings are altered slightly. The serial numbers indicate only the production order of the amp within the series. Finally, Smith talked to Richards and they agreed that he would send them an amp, and that the Stones would pay for it or return it. There is no date information coded into the serial number.

There was also a reverb option which replaced the Middle knob with the reverb control knob. However, the loop was placed between two critical gain stages, and tended to overdrive some instrument level effects, and also caused volume pedals to act as remote gain controls for the lead mode.

Richards had played Santana's Boogie and decided he wanted one too. It also features cab clone. Ignore the remainder after dividing the serial number. The exact age of a Mesa Boogie amp can be determined only by requesting Mesa Boogie to check the serial number of the amplifier against its records. The amplifier was voiced so brightly, it is considered to be the most aggressive Mark Series Boogie ever introduced.

The combo is a similar size to the Mark I combo.

Each revision had a slightly different voicing, but identical functionality. Indeed, the mark itself can be forged.
