Gallien-Krueger Legacy 500 Bass Amplifier Head (450 Watts)

zZounds Gear Experts Say...
A modern celebration of the history of Gallien-Krueger, the Legacy 500 bass amp features 450 watts of power, a 4-band EQ, and 4 and 8 ohm load capacity.

The Legacy Series represents fifty years of design, innovation and industry experience at Gallien-Krueger. Because the Legacy Series shares the same designer as the 800RB, it shares the same DNA and the same level of innovation, with a more evolved feature set and construction concept.

Features:

- Four band active EQ
- Foot Switchable Overdrive with Tone Control (Footswitch Included)
- "Bump", "Contour", and "Presence"
- Voicing Filters
- Balanced XLR Output with Pre and Post EQ
- Unbalanced 1/4" Send and Return
- Aux Input and Headphones Output
- Twist Lock Speaker Outputs

The introduction of the 800RB in 1980 cemented Gallien-Krueger as a leader in Solid State bass amplification, with its signature growl, clarity, power, and features that were ahead of its time. The Legacy Series of heads captures that same aesthetic while adding something all its own. From clean, clear, biting tones, to saturated overdrive, the Legacy series has it all. Coming in 500, 800, and 1200 watt class D models, The Legacy Heads are ready for the biggest stages, the smallest living rooms, and everything in between.

To improve performance and reliability, the Legacy Series uses a unique interconnection system that eliminates problems that can develop over time from constant vibration and temperature extremes that gear is subjected to with heavy use. Using circuitboards with gold plated connectors, rather than cables with standard tin connectors, this type of construction delivers a more pure, read more reliable sound. Features include GK's classic 4 band EQ, Overdrive complete with tone shaping, additional voicing filters such as "Bump", "Contour", and "Presence", Balanced DI with Pre and Post EQ, an Effects Loop, Aux and Headphone connections, and Load capacity selection, to deliver optimum power into 2, 2.7, 4 and 8ohm cabinet configurations.

"GK 800RB Replacement"

Overall: 5 out of 5 stars

Verified Purchaser zZounds has verified that this reviewer purchased this specific product from us.
I bought the GK 500 Legacy to replace my old 1994 GK 800RB which I still own and love but as a gigging bass player I needed something that had a few more options and was newer, not quite so USED. The GK 500 Legacy does all that and more, carrying the same tone and growl as the 800RB, but has a mute switch (possibly the most used) the boost channel activated with drive, which really adds a classic, darker tone and then bump, contour and presence which really gives the amp a huge range of tonal possibilities. It's been a work horse since I got it and I couldn't be happier with my purchase from zZounds and GK. They've kept me playing live music since 2013.
