Capture the unmistakable warmth and dynamic response of a true vintage American classic with the Synergy BMAN 2-Channel Preamp Module, available now at Haggerty’s Music. Inspired by one of the most influential amplifier designs of all time, this module delivers the rich tonal foundation that helped shape blues, rock, and beyond.

Built around the legendary tweed-era Bassman sound, the BMAN module recreates the signature blend of warm low end, sparkling highs, and smooth, harmonically rich breakup. Its dual-channel design allows players to move effortlessly between clean, articulate tones and pushed, vintage-style overdrive. Each channel features independent gain, volume, and three-band EQ controls, along with bright and tight switches that let you fine-tune response and tighten the low end for modern performance needs.

Designed for flexibility and authenticity, the BMAN integrates seamlessly into the Synergy modular ecosystem while maintaining compatibility with select legacy systems. The cathode select switch allows players to adjust feel and low-frequency response, while the dual/single mode ensures adaptability across different rigs. Whether you're chasing classic blues tones, roots rock grit, or a responsive pedal platform, the BMAN delivers the foundational American amp sound in a compact, powerful format.
