Here is a brief description of the B-Band Crescent 2 pickup which is available on all acoustic models except the Skylark.
The B-Band Crescent 2 XOM (cross-over-mix) has two inputs for UST and AST pickups. The XOM circuit achieves the highest possible quality in acoustic sound. It enjoys the benefits of both an under saddle transducer and a soundboard sensor, all overseen by an 800Hz crossover.
The controls are mounted at the soundhole and include volume; XOM blend control, UST and AST input gain controls, phase button and low battery / “flash” ON indicator LED. The controls allow the player to blend the two sources to achieve a perfect mix of bass and treble. The bass is very good without being domineering and the trebles retain their melodic personality.
