For over five decades, Gallien–Krueger has pioneered amplifier innovation and maintained their commitment to U.S. manufacturing excellence. The company’s Microbass and MB Series combos established industry benchmarks for performance and portability that continue to shape the market today. Now, building upon this rich heritage of cutting–edge design and in–house manufacturing expertise, GK introduces the Legacy Series combos – a fusion of legendary tone, robust power, professional–grade features, and exceptional portability crafted specifically for working musicians.
At the core of each Legacy Series combo lies the sophisticated Legacy preamp, which carries the genetic blueprint of the iconic 800RB. This preamp represents the pinnacle evolution of one of bass amplification’s most celebrated designs. The comprehensive feature set includes GK’s signature 4–band EQ, foot–switchable overdrive with dedicated tone control, and additional voicing filters including “Bump”, “Contour”, and “Presence” options. Modern connectivity is covered with balanced DI offering both pre and post EQ options, effects loop, auxiliary input, and headphone output connections.
The Legacy range offers remarkable flexibility with speaker configurations spanning 1x12, 1x15, 2x10, 2x12, and 4x10 arrangements, all featuring premium Neodymium drivers designed and manufactured at GK’s California facility. Each combo is powered by an advanced 800–watt switch–mode power amplifier that provides the muscle needed for large stages and outdoor venues, whilst incorporating universal power compatibility for seamless operation across 100 to 240–volt systems. This versatility makes the Legacy Series equally suited to intimate local sessions and demanding international touring applications.
