"This is a 1970s Moog MKG 10 band graphic equalizer. Sometimes people disparage graphic equalizers in favor of parametric equalizers. Some people say graphic equalizers are for killing microphone feedback in live rooms, or cutting an unruly resonance in that live room. True, graphic equalizers focus on specific bands, but the shape makes a difference, and Moog knew what they were doing back in 1970s.

We’ve had this for a while and have used it mostly on things like our Roland TR 606 or our Korg MS-20. For the 606, raising the 2k band way up and the 4k up a bit, while dipping the 8k band can make those famous hi hats pop with more presence and less shrill. 63 makes the kick thump. For other things, like synths, I’d just boost the 31 or 63 Hz band to pump it up, warm it up, round it off.

The ears are ingenious. This whole line—the phase shifter, the parametric, this graphic—have reversible ears. Orient them one way and you can rackmount it in any 19” rack. Orient them the other way and you have handles that are cleaner to look at when used desktop-style.

The sliders have an indentation at 0, so you can always feel and find your way back to null.

It sounds great and there is no scratchiness. The only issue is the 1k band, which sometimes glitches at the very top or very bottom of the slider. When we got this it was filthy. I cleaned the grooves within the ears, as there was crud in them. I cleaned grime out of the slider tracts. And dusted the inside. I sprayed the 1k band with deo it, which improved the 1k band’s performance a bit, but if you are buying this to do fancy live wiggling of sliders, maybe get another one—or buy a Synthesizers.com fixed filter bank. I’d recommend this more for someone who needs it for seeking a sound, accentuating certain frequencies, or doing weird bandpass-ish comb-ish stuff. That said, they’re all perfect except the 1k. The 250 is the stiffest, the rest are smooth."
