Most iconic of the 70’s ‘aluminum guitars,’ the Travis Bean line up continues to remain a valuable collector’s item. Famous players include Duane Dennison from this classic band. You can see a more detailed list at this link. I briefly played the much crappier Kramer aluminum-necked instrument from the same era; it had a terrible two-bolt neck joint that never seemed to stay tight. Frequent unintentional chorus-ing would result. Any TB fans out there?
