MESA/Boogie Mark IV Model B 1x12" Custom Hardwood Combo

The Mark IV amplifier series is celebrated for its compact size, impressive power, and versatility. It's considered the pinnacle of guitar amp evolution and remains in active use by many musicians. It offers three distinct sound modes: Rhythm 1 for a lively, fresh tone, Lead Mode for high-gain intensity, and Rhythm 2 for a versatile middle-ground sound that can handle clean, bluesy, or crunch tones. Additionally, the Mark IV features Simul-Class technology, a patented method that combines the sweetness of Class A power with the punch of Pentode Class AB, enhancing the power section's performance.
