David took the idea of the ASAD and adjusted it to suit his needs. What has he done? The scale length is 25" with 22 frets, the trem is the non locking Schaller Vintage (which mounts on two studs and knife edges with roller saddles), the controls have been moved away from the playing area and the socket moved to the end of the body. The dot inlays on the ebony fingerboard are abalone. A GraphTech nut is fitted and, along with the bottom locking Schaller machines, this helps with tuning. The top of feathered Irish walnut is carried over the arm relief and glued to the utile body core. The back plates are utile too.
The circuitry is interesting in that the push-push tone control makes the pickups (Seymour Duncan Jazz and JB) single coil or humbucking while the miniswitch acts to connect the two pickups together in series and overrides the 3 way slider offering a volume and mid-range boost. Simple but very effective these controls give a wide range of tones with minimal fuss. A class act.
