Sam Grisman Project has announced plans to play a pair of famous instruments—namely, Jerry Garcia‘s TB500 #12 guitar and Phil Lesh’s custom “Mission Control” bass—during the band’s upcoming performance at Belly Up Tavern in Solana Beach, CA on Wednesday, February 12th.

“Although playing acoustic music through condenser microphones has been our primary focus in SGP for quite some time, when the opportunity presents itself, we love to plug in and rock out!” Grisman noted in a social media post. “There’s no better excuse to go electric than to get to visit with some true relics that participated in some watershed moments in Grateful Dead history.

“Thanks to our friend [Jason Scheuner] we will have the pleasure of playing two instruments that were a quintessential part of The Dead’s sound in ’77,” he continued. “I grew up in a house full of old mandolins, guitars, and banjos and I have always had an appreciation for the history of these instruments and the stories that they seem to tell us. I am deeply grateful to get to share the experience of playing these legendary larrys, which made some of my favorite music in the hands of some of my favorite musicians, with our friends down in the San Diego area at [Belly Up Tavern].”

Grisman went on to detail how the instruments were used during the live debut of “possibly my favorite Garcia/Hunter song, ‘Terrapin Station’,” a tune that Sam Grisman Project recently debuted themselves at Portland, OR’s Aladdin Theatre, and to record the album Terrapin Station. “The sounds of these instruments are truly engrained in my musical subconscious, and it is a profound honor to get to reunite them on stage to play some of my favorite music.”

Jerry Garcia debuted the TB500 #12 guitar on December 31st, 1976 at the Cow Palace in Daly City, CA and played it at more than 90 shows in the late ’70s, including at what many consider to be the Grateful Dead’s greatest show ever, 5/8/77 at Cornell University, and the Grateful Dead’s three-night stint at the Winterland Ballroom in 1977. It was the third-most-played by Garcia—behind “Tiger” and “Wolf.”

Phil Lesh’s famous “Mission Control” bass, a.k.a. Osiris, is a custom Alembic bass hand-built by luthier Rick Turner and played by Lesh with the Grateful Dead from June 16th, 1974 until July 1st, 1979, including at the Cornell show. The instrument helped set the standard for boutique basses with its many cutting-edge features, among them ten small push-button switches that gave Lesh the ability to send the signal from each string to four separate stacks of nine 15” speaker cabinets in the Grateful Dead’s Wall Of Sound PA system.

The same two instruments were recently played by Dogs In A Pile during their visit to San Diego. Check out videos here.
