Legacy 500: The Next Generation of GK Bass Tone

This article was Written By

Our Product Research Team

Get to know them!

The Gallien-Krueger Legacy 500 is a 450-watt compact, lightweight bass amp head with a Class D switch-mode power amp and analog preamp with overdrive. The Legacy series represents a half-century of industry-leading innovation at Gallien-Krueger. With its signature growl, clarity, power, and features that were ahead of its time, the 800RB, launched in 1980, established Gallien-Krueger as an industry leader in solid-state bass amplification. GK's Legacy series heads conjure the same no-nonsense aesthetic while delivering cutting-edge sound and features for today's bassists. From clear, biting cleans to fat, punchy overdrive, the Legacy series can do it all. Packing 450 watts of Class D power and smart, flexible features, the Legacy 500 is gig-ready for studio sessions and live venues of any size.

Quickly nail the tone you need for any gig

Legions of bass players at Sweetwater trust Gallien-Krueger to deliver the tone, gig after gig. That's why GK designed its Legacy series bass heads with a flexible, smart feature set to help you ace any live show or recording session. Sculpt your tone to perfection with Gallien-Krueger's classic 4-band EQ. Quickly audition versatile voicing filters — Bump, Contour, and Presence — to zero in fast on the perfect sound for any music genre. Kick in saturation with onboard Overdrive, and dial in Edge tone-shaping to taste. Whether you're playing prog metal or country, the GK Legacy 500 fits the bill.

All the right connections

On the Legacy 500's rear-panel Patch Bay, use the effects loop Send and Return to connect your favorite compressor or other outboard gear. Landed an arena gig? Use the balanced DI output to send a post-EQ signal to the PA. In the studio, switch the DI to pre-EQ and connect directly to the recording console. From coffeehouse gigs to stadiums, the Gallien-Krueger Legacy 500 has you covered with flexible load capacity cabinet impedance switching that delivers optimum power into 2-, 2.7-, 4-, and 8-ohm loads. Practicing quietly at home? The GK Legacy 500 also features Aux input and Headphone jacks.

A gig-ready, tour-tough head

To improve performance and reliability, GK's Legacy series uses an innovative interconnection system that eliminates issues that can develop over time due to the frequent vibration and temperature extremes that gear is subjected to with demanding professional use. Legacy series circuit boards use gold-plated connections instead of standard cables with tin connectors. This type of robust construction delivers a purer sound in addition to the enhanced reliability to withstand years of heavy touring.
