Owner’s Manual Hello from the Tone Farm Congratulations! The amplifier you have chosen is born of thoroughbred stock that carries worldwide accolades and is still setting trends with top Artists 35 years after its unveiling. The MARK FIVE: 25, like the MARK FIVE it is born from, is really a collection of iconic amplifiers. There are far too many circuits and sounds to think of it as merely an amp... it’s a living history of MESA/Boogie! From the groundbreaking MARK I that introduced the world to high-gain with it’s cascading preamp, to the Mark II, the world’s first high gain Dual Mode Channel Switching amplifier (and it’s later siblings that introduced Simul-Class™ power). From the MARK III that ushered in the era of 3 Channel footswitching. performance, to the MARK IV which gave all that power individual control, the MARK FIVE (and now the MARK FIVE: 25) is the embodiment of the last 45 years of guitar amp evolution.
In this latest 25 Watt incarnation, the sounds and attributes that make MARK Series amps so popular on stage and in the studio are not only shrunk to their smallest possible physical size, but are also further refined and improved. The gorgeous sparkling Cleans and soaring high gain Lead sounds have made the jump successfully across output tube platforms and a new and exciting timbre of the MARK Series voice is created here in the MARK FIVE: 25’s EL84 Duet. Brighter, tighter, more shredding in the top end, a bit more forgiving in feel and exceedingly more clip-able, the FIVE: 25 is right on time. Whether introducing the MARK heritage to a new generation of low wattage devotees, or fulfilling the ultra-portable Tone Dreams of steadfast MARK Series fans, the MARK FIVE: 25 has got what it takes to inspire and fuel your passion in the most manageable package ever!
