The FET III is a dual-channel limiter from Geoff Daking, built in the U.S. with the same audio path and detector circuits as the single-channel Daking FET II limiter.

The FET III compressor circuitry and gain stages are all discrete and fully Class A. Other than its two-channel build, other new features of the FET III (compared to the FET II) include variable high-pass filters from 0 to 200 Hz; all controls except “Ratio” are pots; THAT Corp. differential amps in and out (electronically balanced), and more.
