MARK IV
Congratulations for choosing the MARK IV as your new musical voice. You have purchased a handbuilt instrument of the finest
quality and craftsmanship. In 1984 Mesa/Boogie introduced the world’s first “Tri-Modal amplifier - the MARK lll - with separate
modes for Clean Rhythm, Crunch Rhythm and Lead Overdrive. Now the MARK IV concentrates six years of intervening design
experience into a masterful new instrument which promises years of musical enjoyment.
Every possible useful feature is included, some for the first time ever. Precise, separate adjustment of each mode is simplified by the
complete and logical array of controls...making the MARK IV easier to use than its predecessor. No compromises were tolerated in
regard to performance, reliability or component quality. Individual master-craftsmanship is evident throughout the construction and
testing of each MARK IV. And best of all, the sound quality of each mode is devastatingly accurate! We want your new MARK IV
to be the last amplifier you ever need to buy.
