The ASAT Bass Signature shown here is an interesting transitional example from the BBE period.  The new owners of G&L made sweeping changes almost immediately after taking over the company in November 1991.  This bass has a Leo-era slab body with output jack plate, but the neck is from early 1992 and has different tuner posts (satin finish with shoulder vs. polished aluminum conical), a semi-gloss neck finish (Leo-era necks were high gloss and later BBE-era necks were satin), and a thinner neck thickness behind the nut.  This bass retains the thin veneer fingerboard of the Leo-era.  Later in 1992, BBE switched to a thick veneer  board and by 1993 the boards were slab.  Most importantly, the BBE-era ASAT Basses (and L-2000s) used a different preamp labelled as Version 1.0 on the circuit board.  This circuit uses a different op-amp and a series/parallel humbucking switch in place of the former coil splitter.  This results in a different sounding ASAT Bass.  Around 1999, G&L revised the preamp once again (Version 1.1) using the original Leo-era op-amp and similar circuit, but retained the series/parallel selector.
