Mesa Boogie - Mark IV - 1x12 85 Watt Tube Guitar Combo Amp - w/Footswitch - x3183 - USED

The Mesa Boogie Mark IV 1x12 85-Watt Tube Guitar Combo Amp is a legendary all-tube amplifier known for its unmatched versatility and tonal precision. Handcrafted in Petaluma, California, it features Simul-Class™ power with four 6L6 power tubes and five 12AX7 preamp tubes, delivering up to 85 watts of rich, dynamic sound. The amp offers three fully independent channels—Rhythm I, Rhythm II, and Lead—each with its own gain and master controls, allowing players to dial in shimmering cleans, bluesy crunch, or blistering high-gain tones. A five-band graphic EQ, assignable to any channel, adds deep tonal sculpting capabilities, while built-in spring reverb, an effects loop, and multiple voicing switches (Pull Bright, Pull Fat, Lead Voicing) make this amp a true studio and stage workhorse1.

The 1x12 combo format includes a Celestion Black Shadow speaker, housed in a rugged cabinet with casters for easy transport. Despite its compact size, the Mark IV delivers massive sound and flexibility, with switchable output modes (Simul-Class/Class A, Pentode/Triode) and a Full Power/Tweed “Variac” switch for dynamic control. A six-button footswitch allows seamless channel switching and EQ/FX loop activation, making it ideal for live performance. Whether you're chasing vintage warmth or modern aggression, the Mark IV stands as a pinnacle of Mesa Boogie’s amp design legacy, offering a tone palette that suits virtually any genre or playing style/.
