This is a 4 band fully parametric mastering EQ. It's based on the KHN State Variable Filter used in many consoles and rack EQs, most notably the Barry Porter NetEQ. I'm currently in the process of revising the design and new features are on the way! Sound samples and technical specs will be forthcoming.
This unit is built to order and all of the controls are customizable along with the front panel design. All of the controls use high quality Grayhill and Elma rotary switches. The current price is $5000 for a full quality mastering grade build. Please don't hesitate to contact me if you are interested or have any questions.
