Selling a GML 8200 stereo parametric equalizer, first series — the reference-standard EQ from George Massenburg, the engineer who coined the term "parametric equalization" itself. Includes the external power supply.

The 8200 is an all-discrete, Class A stereo parametric EQ with five broadly overlapping bands per channel, each offering up to 15dB of boost or cut with continuously variable Q from 0.4 to 4. The lowest and highest bands can be switched to shelf mode for added flexibility. Built with precision carbon-film potentiometers, GML's proprietary 9202 discrete op-amp, and a DC servo-stabilized direct-coupled output, it remains the go-to standard for stereo bus and mastering work — prized for its transparency, headroom, and surgical precision.

Condition: Serviced by the official importer just before COVID, and has seen very little use since. The potentiometers can be a bit noisy/crackly when turned — a common trait on units of this age — but the unit performs well otherwise.
