We were among the very first dealers to bring Phil Jones amps to the US market, and we've brought them back on board!

Mark's TakeThe "Micro 7" is a highly compact combo featuring a 50w power amp driving a 7" woofer and 3" tweeter. Weighing in at only 15 lbs, and smaller than 1 foot in every direction, it's super easy to tote around, and is a great amp for small electrified gigs or reinforcing the acoustic volume of your upright bass in small to mid-size combo groups.
