Well, what can I say about this one? The word most often used to describe the Bass VI is "Misunderstood" the Bass VI wasn't the first baritone guitar but it was the one which on its initial release had a lot of bass players picking it up figuring it was a new of extended range instrument. Only to find out that it actually isn't a Bass at all, it's a guitar tuned down an octave and many high profile players such as John Entwistle and Noel Redding gave up on the instrument altogether. And the Bass VI ended up not being made in all that large numbers and soldiered on until the mid seventies, when it was discontinued. But that doesn't mean that there wasn't any cool tunes where it was used. Let's start a list of songs where the Bass VI was used. First up, probably the earliest users of the instrument: the Tielman Brothers. Note that they used their Bass VI's in two ways, one as a pure bass and the other as a low tuned twang machine. And it was in the second role where the Bass VI found its niche as bands discovered that doubling guitar riffs on a Bass VI happened to sound completely bad ass. Joe Perry said that he learned about the Bass VI when Peter Green mentioned it in an interview, after which he went "I'm going to have that sound for myself." And the Low tuned Twang also added some real menace to a tune when used on its own, as many country players already knew thanks to their use of Danelectro baritone guitars. Imagine that sound finding its way onto the songs by a Glam rock band, but that's exactly what happened with Hank Knife and the Jets. But it was in the hands of a disenfranchised English boy and his love for new wave bands such as Joy Division, that the Bass VI found its way into the eighties. What Robert Smith is doing with his Bass VI is basically aping what Joy Division bass player Peter Hook did on his Shergold Marathon six string bass. But Smith added very intricate melodies to that sound. But perhaps the most famous band to ever use the Bass VI must be the fab Four, where both George and John used it whenever Paul was on the piano or on guitar. It is John laying down this surprisingly funky bass line on this song.
