The Mesa Engineering Big Block 750 is a high-powered, all-tube bass amplifier head designed for bassists seeking massive tone, punchy low-end, and rock-solid reliability. Delivering 750 watts of RMS power at 2 ohms, this amp head features a hybrid design, combining a 12AX7 tube preamp with a solid-state power section, giving players the warmth and harmonic richness of tubes with the clarity and tightness of solid-state efficiency.

Its intuitive front panel includes Gain, Bass, Mid, Treble, and Master controls, along with a parametric Mid control and a powerful Compressor to shape and tame the dynamics. The Active/Passive input switch ensures compatibility with a wide range of basses, while the DI output, effects loop, and Slave out make it ideal for both studio and stage setups. Built with Mesa's signature rugged construction, the Big Block 750 is a favorite among touring professionals and tone purists alike.
