The Phil Jones Bass Double Four Plus (BG-80) is a remarkably compact bass combo that delivers performance far beyond its size. Pushing 90 watts of clean, articulate power, this amp provides tight low-end response, focused mids, and clear top-end detail—making it ideal for players who need serious tone in a highly portable format.

Built around Phil Jones Bass’s extended-range speaker technology, the Double Four Plus produces surprising depth and clarity without the boominess common in small enclosures. Every note remains defined and balanced, whether you’re practicing at home, recording in the studio, or covering intimate live settings.

Lightweight yet professional in output and control, the BG-80 is perfect for bassists seeking a compact solution that doesn’t compromise on sound quality. It’s an excellent choice for rehearsals, travel, small venues, or as a premium personal monitor with signature PJB clarity.

Practice hassle-free with either a stereo aux in or Bluetooth 5.1 to play along with your favorite tracks, both with their own dedicated volume level. And when its time for headphones they have their own dedicated volume, too.
