To celebrate the launch of Hard Rock Cafe’s most extensive menu innovation in the company’s history, they’ve released “The Golden Solo,” a guitar solo played on the world’s first playable burger guitar.

The one-of-a-kind guitar was crafted by famous guitar maker James Trussart, whose clientele includes Keith Richards, Bob Dylan, Paul Simon, Eric Clapton, Charlie Sexton, The Roots and Mick Jagger. The instrument is powered by Hard Rock Cafe’s 24-Karat Gold Leaf Steak Burger, and uses the player’s body to conduct a unique electrical current through the burger, similar to picking the strings of a guitar.

Through a single-board micro-controller that was wired into the digital guitar’s circuitry, the player’s body completes the circuit within the processor to produce sound. The guitar takes electrical currents from the burger’s ingredients and turns them into audio tones, so that the guitar can actually be played.

“I’ve built guitars for more legendary rock stars than I can count but never a guitar for a legendary burger. It was a totally different kind of challenge and an honor to work on,” said Trussart. “The burger, of course, was delicious.”

The 24-Karat Gold Leaf Steak Burger is comprised of a 1/2-pound fresh Steak Burger topped with 24-Karat edible gold leaf, Tillamook cheddar cheese, leaf lettuce, vine-ripened tomato and red onion. Through the Hard Rock Heals Foundation, a portion of the proceeds from all sales of the burger will go toward Action Against Hunger to help in the fight against world hunger.

“At Hard Rock Cafe, we have no greater passions than food, music and our guests. ‘The Golden Solo’ brings together food and music in a unique way that truly embodies our brand and adds fun to our guest experience,” said Stephen K. Judge, president of cafe operations at Hard Rock International. “As we launch the most extensive menu innovation in Hard Rock Cafe’s history, ‘The Golden Solo’ gives our fans yet another way to see, taste and hear all that Hard Rock Cafe has to offer.”

The release of “The Golden Solo” coincides with the launch of a new menu for the cafe, which features over 20 innovative offerings.
