This version used a bridge that did not appear on any other Westone - the saddles are barrel shaped like the saddles on the Thunder basses, and there are slots in the bottom for quick string changing, which makes it look like it has through body stringing.

HF450 pickup
Through body stringing with the same bridge and rear string retainer as used on the Thunder I and IA

Unlike other active Westone guitars, the Paduak I only uses one battery

Two versions of the Paduak I appear in the April 1983 US pricelist, one without a trem at $299.50 and one with a trem at $329.50. None of the catalogues mention a model with a trem.
