A lighter guitar body is easier to balance on your body for extended periods of time when playing gigs. It can also resonate louder. Akin to hollow body guitars they are typically lighter even though they are solid body guitars. Lightness makes them more comfortable to play for long gigs.
Feather light electric guitars are somewhat rare. We build these for players every week at Haywire Custom Guitars. The body is baked Swamp Ash. Here is a link to a video for you. Greg Dalton, music director of Legends in Concert Myrtle Beach is playing the same guitar with humbuckers: https://youtu.be/i5H_ajv4KIU We build many of these for older players, players with neck and back issues and guitarists who just want a very light guitar. Guitars for all players need to be very easy, light weight, well balanced, easy to maneuver and enjoyable to play. Our Featherlight guitars from the Custom shop are easy to hold, play and balance. At Haywire Custom Guitars we take the classic look of the double and single cutaway guitars and lighten it and drop the weight by up to 30 percent by baking the moisture out. As a result, each Swamp Ash body we build is Featherlight.
