Our goal was to create a new standard in bass amplification. After 5 years of design work, 20 revisions, and thousands of hours in the lab, we’ve created an unrivaled analog bass amplifier. Unprecedented performance, studio quality sound, boundless features, punch that never quits, indestructible analog power, and a metal enclosure machined to perfection. The 1001RB and 2001 RB Legacy achieves everything we set out to do and more. This is the new standard of excellence for the modern professional bass player. #gkallday #gallienkrueger #namm2025 #nammshow #bassplayer #bassmagazine #bassamp #bassguitar #bassist
