Westone Leader

Single humbucker, volume and tone controls, coil tap switch, standard trem. The shape is very similar to the early Concord I and the Paduak.
Ttwo versions are listed in the April 1983 US pricelist, both available only in a natural finish, one with a trem at $219 and one without a trem at $195, making the Leader the cheapest model available at the time. This model does not appear in the 1982/3 or 1983 catalogues, and only appears in the April 1983 US pricelist, so may only have been available in early/mid 1983.
