AC FB Humbucker:
This hum cancelling pickup uses coils which are rotated through 90 degrees with magnets inside them placed against a single blade of steel running the length of the pickup. This gives the advantage of hum cancelling while still maintaining the narrow magnetic aperture of a single coil. The bridge and neck versions have different gauges of wire and number of turns giving added versatility to the sounds you can get from your ACG bass.
The FB Pickups are the first port of call for all ACG custom basses, and represent a more open, high fidelity tone giving a great balance throughout the register of the bass guitar.
About ART (Acrylic Resin Treated) Woods
The ART Hybrid Maple Burl top is not just visually stunning—it also enhances stability and resonance. For over 20 years, Alan has refined the use of acrylic-impregnated woods, creating highly figured tops that are as visually stunning as they are durable. The ART/Hybrid process, developed in collaboration with the late Larry Davies, results in one-of-a-kind color patterns and textures, making each bass a distinctive work of art.
