This is the Fender ACB 50: the Adam Clayton signature bass amplifier. Designed in collaboration with the legendary U2 bassist, the ACB 50 is a comfortably sized 1x15" all-tube combo amplifier that offers warm, harmonically rich tube tones that are perfect for the studio, club or arena stage. Featuring two distinctly different channels – a classic Fender sound and a more modern hi-fi, flat EQ tone, the ACB 50 achieves all the sounds you need in any musical situation. Classic cosmetics, chrome panel and chicken head knobs replicate that classic Fender look that players around the world have come to love. The ACB 50 includes a lightweight Eminence® Neo 15” speaker that helps accentuate its fat, powerful sound and features an XLR line out to send that great tone to your home recording rig or front-of-house.
