SOLD - Mesa Boogie Mark IV Combo Amplifier - USA 2003

Here is a Mesa Boogie Mark IV single 12” combo amplifier, a compact yet extremely powerful 85-watt all-tube amp widely regarded as one of Mesa’s most versatile and high-performance designs. Despite its relatively small footprint, it delivers enormous tonal range and stage-ready volume, making it a favourite among players who need one amp to cover everything.

Built around a three-channel architecture with extensive footswitch control, the Mark IV moves seamlessly from crystalline clean tones through to saturated high-gain distortion. Its flexible voicing and deep switching options allow for a wide palette of sounds, from articulate cleans to aggressive modern lead tones.

A standout feature is its highly responsive EQ and gain staging structure, with pre-gain tone shaping and a post-gain five-band graphic equaliser. This allows for precise sculpting of both drive character and overall tonal balance. Pushing treble into the gain stages yields bright, cutting lead tones, while boosting lows and low mids before gain produces thick, saturated textures ranging from classic rock drive to fuzz-like intensity.

This example is presented in near-new condition, with all controls, switches, and functions operating exactly as intended. The grille cloth is clean, and the tolex shows no visible wear, reflecting careful ownership and maintenance.

The Mark IV also features a powerful spring reverb circuit and a harmonic mode that enhances sustain and musical feedback, making it particularly expressive for lead playing. Despite its weight and density (37.6kg), this is a highly portable all-in-one professional amplifier capable of covering virtually any genre without the need for additional pedals.
