Westone Thunder IIA

There are at least 3 versions of this model. As with the Thunder IA, the earliest version has variable gain for the active circuit, later versions replace that with separate active and passive tone controls

Version 1 (1981-82)

As shown in the 1981 catalogue:

The serial number of the guitar below dates it to 1981. Thanks to Ronnie for the pictures. (The single coil pickup and extra switch are not original.)

Version 2 (1982-3)

Here are technical specs of the Thunder IIA in the 1982/3 catalogue, but no pictures of it

It is possible that the specs in the 1982/3 catalogue are wrong. The guitar below dates from early 1983, but has the earlier version of the active circuit. (Volume, tone, active gain controls)
