Gallien-Krueger has been on the leading edge of bass amp design and technology for over 45 years. On a sunny afternoon in 1968, Robert Gallien walked into his local music store, carrying an amplifier he had made in his garage. 47 years and thousands of amplifiers later, Bob Gallien is still designing some of the most innovative and highly sought after products on the market. His creations enjoy a heritage of recording and stage performances with the world’s most discerning artists.
All Gallien-Krueger products are designed and manufactured in the U.S.A. and have been throughout the company's history.
"I’m a Stanford educated engineer who worked my way through school as a musician. As I am the principal innovator at GK, our products reflect my attitudes and life experiences. I don’t model my designs after other manufacturers’ products. Instead, I search for new and better solutions. GK products enjoy a unique, unmatched sound, allowing you every opportunity to make an original statement."
The original micro bass amplifier, without compromise
Gallien-Krueger were the first company to recognise the full potential of class-D / switching amplifiers and their application to bass guitar amplification.
This technology is ideally suited to the clean, precise and balanced sound that so many contemporary bass players seek, and is implemented to perfection in their MB series bass amplifiers.
These ground-breaking designs greatly reduced the size and weight requirements for bass amplifiers, without sacrificing power or performance and set a new bench mark for portability that so many other brands have since attempted to emulate.
Always listening, to deliver what bass players want
The PLEX preamp combines 47 years of amp design experience with state of the art technology to deliver the flexibility today's musicians require.
The heart of every GK product is the active 4 band “variable Q” equalizer and contour circuit that set the standard for bass tone shaping over 30 years ago.
Building on this proven foundation, the PLEX features expanded filter options that allow you to further dial in your instruments unique voice.
Foot switchable Compressor and Overdrive ensure your performance blends seamlessly into the band or cuts through a crowded mix and the Chromatic Tuner makes sure it’s all in tune.
