Stevie Ray Vaughan & Jimmie Vaughan "Pipeline" (on a double neck guitar!)

The Vaughan brothers, (Stevie Ray and Jimmie) play the surf instrumental, "Pipeline" (incidentally, recorded in 1962, by surf rock band, The Chantays), on a double neck guitar, at the 1987 New Orleans Jazz & Heritage Festival, aboard the S.S. Presidente riverboat.  The guitar Stevie Ray and Jimmie are playing, incidentally, is a custom made piece by Robin Guitars out of Houston, Texas, that resembles a Fender Stratocaster, and has two maple necks (each with a different scale length), a pointy "drooped" headstock with locking tuners, and Rio Grande single-coil Stratocaster style pickups. 

The guitar is/was known as "The Family Guitar", and for good reason.  This is part of a series of videos.  Check it out.
