Version 2 (1982-3)
As shown in the 1982/3 catalogue.
- Body/neck wood specs as above,
- Westone script logo on the headstock, plain brass knobs.
- Different bridge with through-body stringing.
- 2 HF450 pickups
- Different active circuit - controls are master volume, passive tone, equalizer tone. This circuit has the same tonal control range as the earlier one but the gain is not adjustable. (Though as with the Thunder IIA the catalogue specs may be wrong - some early 1983 models still had the original adjustable gain active circuit)
