How Mesa founder Randall Smith managed to engineer six different amplifier modes into this tiny head is nothing short of a mind blower, and the result is a unit that delivers more sounds per pound than any all-tube amplifier on the market. With its “library” of classic Boogie circuits, multitude of hip features, and elegant interface, the Mark 5 Twenty-Five represents a quantum leap in guitar amp technology and earns an Editors’ Pick Award. Switching to channel 2 unlocks the Mark 5 Twenty-Five’s classic Mesa/Boogie side by providing an excellent replication of the famed Mark IIC lead channel.This feat was proven in the Mark 5’s ability to nail the high-gain magic of the IIC , so it’s not surprising that the Mark 5 Twenty-Five also dishes out that same deliciously saturated grind.The introduction of the Mark 5 a few years ago seemed to be the last word from Mesa/Boogie in terms of packing the company’s “greatest hits” amps into a single chassis.This highly successful three-channel amplifier has paved the way for the smaller two-channel Mark 5 Twenty-Five, which has two EL84 power tubes in place of its bigger brother’s quartet of 6L6s.

Mark IIC /Mark IV/Xtreme switch, Multi-Watt switch (10 watts/25 watts). Weighing in at only 16.5 lbs and measuring 14" wide, this radical amp offers six style modes, along with a load of features, including independent controls for each channel, a footswitchable 5-band EQ that can be assigned to either or both channels (or bypassed completely), and a Cab Clone cabinet simulator that, like the stand-alone version (reviewed in the January 2015 issue of Channel 1 has a mode switch that toggles between Clean, Fat, and Crunch settings, while channel 2 lets you select Mark II C , Mark IV, and Xtreme modes.Other details include a tube-buffered effects loop, tube-driven spring reverb with independent channel controls, and a Multi-Watt switch on both channels that lets you independently select 10- or 25-watt operation.Randall Smith was born into a musical family in Berkeley, California in 1946.His mother and sister played piano and his Father was the first-chair clarinet with the Oakland Symphony Orchestra, played tenor sax, had a radio show and led a hotel dance band.
