This is one of the early Englehardts with the exterior linings and other features more similar to the parent company, Kay. Professional  repairs just completed including a REMOVABLE bolt on neck for easier air travel, New adjustable bridge and, very importantly, carbon fiber reinforcement added to neck for stiffening to make the bass easier to play and  stronger as Englehardt basses have very slim necks that bend without a heavy fingerboard or a carbon reinforcement.  Big projecting sound.
