Check out renown bassist Xavier Padilla as he solos on his custom Little Guitar Works bass in this live 2005 London performance with the Gipsy Kings:
Padilla was suffering from wrist problems when he approached Jerome Little of Little Guitar Works for this amazing custom instrument. Specifically, Padilla was suffering from deQuervain’s Tenosynovitis, a form of tendinitis. Take particular note of the radical Torzal twist neck which reduces strain on the fretting hand by allowing the guitarist to play with a straighter wrist when on the lower frets.
