Meet the modern heir to the legendary 800RB: the Gallien-Krueger Legacy 800. This 800-watt powerhouse distills 50 years of Bob Gallien's design mastery into a compact head that weighs a mere 5.8 pounds. It’s lighter than your pedalboard, yet powerful enough to make the rafters tremble.
From intimate gigs to arena stages, the Legacy 800 delivers that signature GK growl with a clarity and punch that will slice through any mix, all while fitting comfortably in your gig bag.
Powerful and Impactful
Don’t be fooled by its lightweight design — the Legacy 800 packs serious power. Featuring a highly efficient Class D power amp, this head delivers impressive wattage across various impedance setups with ease. Whether you’re using a single 8-ohm cabinet for practice or connecting multiple speakers for a festival gig, the Legacy 800 intelligently adjusts to your rig with adaptable load capacity.
800 Watts of Pure Class D Power: Delivers 400W at 8 ohms, scaling up to a full 800W at 4, 2.7, or 2 ohms for maximum headroom and speaker flexibility
Durable Gold-Plated Interconnection System: Gold-plated connectors on the circuit boards prevent signal loss caused by vibration and temperature changes, unlike flimsy tin cables.
Compact and Lightweight Design: Weighing just 5.8 pounds and measuring 11.5" x 11" x 2.3", this head is easy to transport while maintaining a professional presence on any backline.
Tone Sculpting for Every Genre
The Legacy 800 doesn't just amplify your sound — it sculpts it. Thanks to GK's classic 4-band active EQ and three powerful voicing filters, you can dial in everything from crystalline slap tones to rumbling doom without ever touching a pedal. Factor in the footswitchable overdrive with its own tone control, and you get a sonic palette that shifts from pristine clarity to saturated grit with a single stomp.
Classic 4-Band Active EQ: Sculpt your sound with surgical precision. This intuitive EQ lets you boost or cut Bass (60Hz), Lo-Mid (250Hz), Hi-Mid (1kHz), and Treble (7kHz) to sit perfectly in any mix.
Footswitchable Overdrive with Tone Control: Stomp on the included footswitch to unleash the legendary GK growl. With its own tone-shaping circuit, you can dial in anything from warm, tube-like saturation to a snarling, aggressive bite.
Three Voicing Filters: Instantly reshape your core tone for any genre. Add low-end "Bump," scoop your mids with "Contour" for a classic slap sound or add attack and sparkle with "Presence" for cutting through a dense mix.
Connectivity That Covers All Bases
The Legacy 800's pro-grade I/O makes for effortless integration into any setup. The balanced XLR output provides both pre- and post-EQ options, giving FOH engineers the choice between your pure, uncolored signal or your fully crafted tone. An unbalanced effects loop lets you easily patch in your favorite stomps, while twist-lock SpeakON outputs ensure your speaker connections remain solid through every gig.
Balanced XLR Direct Out with Pre/Post EQ: Send your signal to the mixing console before or after your tone shaping — FOH engineers will thank you
Complete Practice and Recording Features: 1/8" aux input for jamming along with tracks and headphone output for silent practice sessions that won't wake the neighbors
Professional I/O Suite: Unbalanced 1/4" effects loop (Send/Return), dedicated tuner output, and rugged NL2 twist-lock SpeakON speaker outputs for reliable connections night after night
Designed for the Long Haul
The Gallien-Krueger Legacy 800 is more than just an amp head — it's a reliable, road-tested powerhouse crafted by a company that's led the way in solid-state bass innovation since 1980. Bob Gallien remains hands-on in the lab, ensuring every Legacy Series head carries the DNA of the legendary 800RB while embracing modern advancements. Built by bassists for bassists, it’s designed to withstand the demands of touring while delivering the consistent, unmistakable GK tone every night.
