LsL Guitars

Lance Lerman and his team at LsL meticulously handcraft their Classic T-Bone and Saticoy ('T' & 'S' style) guitars in the same way that the original manufacturer did in the 1950's and early 1960's. All the work that goes into producing the extra fine tone and feel of these guitars is done completely by hand. They look, feel, play and sound as close to the real deal vintage guitars as anything on the market. Based in Van Nuys, Los Angeles, LsL concentrate on building the best guitars that money can buy. Every guitar is an ultimate Custom Shop masterpiece!
Their motto is "Never sell a guitar that you don't want to keep".


These guitars are only an example of what we carry and what we can order. In addition to LsL, we also carry Godin, Seagull, Art&Lutherie, Simon and Patrick, and more.

  • LSL Saticoy

    LSL has nailed the tone, look and feel of a classic ‘S’ style guitar. The pickups on the Saticoy are hand wired in house, allowing Lance Lerman to finely tune the tone of the entire instrument. From the low E string all the way up to the highest frets, this guitar sounds incredible.

All the work that goes into producing the extra fine tone and feel of these guitars is done completely by hand. They look, feel, play and sound as close to the real deal vintage guitars as anything on the market.

    The Godin 5th Avenue brings you back to a time when the archtop acoustic guitar reigned supreme. With the soul of a 1950’s archtop, the 5th Avenue is a true vintage spirit of yesterday with today’s level of modern playability.

About Gary

Gary Valeriani

Diablo Guitar is owned and managed by Gary Valeriani.

Growing up in the New York Metropolitan Area in the late 60’s, Gary was fortunate to have studied with some of the great players in jazz, including John Abercrombie, Lee Konitz, Sam Brown and others.

He studied in the Jazz Studies Program at Rutgers University under master jazz musicians like Kenny Barron, Larry Ridley, James Spaulding, and Freddie Waits, all luminaries of the classic Blue Note recordings of the 50’, and 60's. He continues to share his knowledge and insight with guitar students throughout the East Bay.

Selling guitars has been a natural evolution for me as a guitarist. I know and love everything about guitars and I really like helping people connect with great guitars. It's what I do.
