The Mesa Boogie Mark Series is a series of guitar amplifiers developed by Engineering Bureau. It was the performance flagship Mesa until the introduction of the Rectifier series, and amplifiers are very collectable.

The Mark I was first drafted in 1969, more than Smith, as a joke, corrected (Country Joe and Barry Melton The Fish) Fender Princeton amplifier. He removed the criterion of 10-inch speaker and corrects the chassis to accommodate the enlarged transformers which was poor by Bassman 4-10 tweed Fender, the circuit had extra 12 watts of Princeton. Finally, the assembly of 12 "JBL D-120, a Republican speaker of the day, Smith had writing what would be the first Boogie.

Randall Smith took the "hot-rodded" Princeton in the store front. Coincidentally, Carlos Santana dominant, "lamented through that little amp until people were blocking the sidewalk." Impressed, Santana articulated Smith, "The man, that little amp really boogies! "Therefore the delivery of the ongoing call for the amplifier and the company.

"Mark I" is the nickname given to the first Boogies drafted, even as they were not called "Mark I" until the Mark II came. Were 100 or 60 watt combo amp with a speaker 12 inches at the beginning of Altec-Lansing 417-8H Series II. The Brand I partner channels: a bath (voiced fairly interchangeable with the original Fender) called "Entry 2 "and a" big gain ", called" Entry 1 ", making the saturation" Lead Boogie "expressions suited to bulk Carlos Santana particularly in the "Abraxas" album, and later by The Rolling Stones, Keith Richards and Ron Wood including amplifiers to survive from of 1977-1993 and the study of classic albums such as Some Girls and Tattoo You.

This amp in its original range is very collectable, but has no feet capacity for change – one is connected to one or the other input to the tones of a couple. Reverb was optional, and not more prevalent in early Boogies. Later, Mark I provides models with reverb and / or graphic equalizer.

Early models have "was a slave" and "reverb" labeling on the rear Dymo stick they have no "main attraction" competition on the volume controls. Later models had "white Pull" and "Pull Boost "In volume controls. The front panel controls are Volume 1, Volume 2, High, Medium, Low, and the Master. These different models first, with reason, as several of them were "tailored" models, only prepared to various buyers.

Mesa / Boogie has declared the original and reissue the expressions have a place "Looser", as the preamp first couple points in time in the past eventuates tone controls. In the various later Mark II and III models, not is simply a point of time gain in the past the tone controls. This chain is an indication to many competition among owners of Boogie.

The Mark II introduced channel change foot, and it was known as the IIA "Mark" until the Mark IIB was issued. Also available as a boss, which could be hooked over a diagram of different combinations of speakers and also a voice recorder add 1×12 cabinet secret spy voice recorder was typical. However, the reverb circuit is noisy and has developed a foot switch expressions used burst past both of these attributes became later in the CII Marcos. The preamp gain in the IIS Marcos later eventuates and tone controls and, according to Mesa / Boogie, the AI has a "more stringent fled more emphasis on the sound "than the Mark I.

The IIA and IIB, and adapted many late model Mark I amps, a silicon implementation called fetron " instead of one of the 12AX7 preamp and includes a switch for the amplifier configuration for either 12AX7 fetron or operation. The intention of including a fetron was to assess many of the difficulties he joined microphonic 12AX7 tubes in a high-gain situation, the exercise was discontinued later.

The Mark III was released by Mesa / Boogie in 1985. Introduced a third channel, a crisis of "ideal rate expressions between rhythm and lead channels. This amplifier has a many foot switch: a switch replacements standing between existing rhythm mode and how to lead, and one must choose between swimming rhythm mode or the mode of contraction rhythm. The pace in more detail all the ways of their controls, drive mode just heap allocations modes pace in tone, with independent gain control Master volume. The Mark III suspended the show in 1989.
