I can't offer much in the way of info on the Alembic Modified ones, but I CAN on the Stock versions of the short-scale, solid-body ones (there were 2 versions, and I'd owned both personally, prior to getting my first Alembic in '76). The ones as pictured are the 2nd. version (appearing around late '71, and actually known as the Les Paul 'Triumph' Bass), and are identical to the 1st. version (introduced in 1970) with the following exceptions: the 1st. version did not have a tummy contour (and was REALLY heavy!), the controls were rear-mounted, the neck (un-bound) featured dot inlays with a simpler crown peghead inlay, and the low/hi-Z transformer was located outboard the bass via a special cable. There you have it....more than you'd EVER care to know about these beasts!
