Meet the Black Lion Audio B173 mkII — the most portable 1073 British-sound around! The B173 mkII uses the same Cinemag input and output transformers as our B173 Quad for a whopping 70dB of gain, a revamped gain stage, and a lower noise floor for cleaner, lower distortion sound. A front panel D.I. delivers a harmonically rich tone to guitars, keyboards, and synthesizers, and stepped input gain and variable output attenuation allow for perfect control over transformer saturation.
