Neumann W491A Stereo Equalizer

Neumann W491A Equalizer Matched Stereo Pair

Only small cosmetic flaws, scratches.
The two EQs work perfectly, however the red LED on the left side doesn't light up.

Can be seen and tested at Frederiksberg, Copenhagen

From Gearspace.com:

The W491A is a flexible eq with a relatively clean yet slightly aggressive character. It´s ability to go from subtle filtering to extreme EQ-ing effects, makes the W491A a very powerful tool in a small module. The sound is much more “in the face” than the one of the Siemens Sitral W295b or the Neumann PEa (W495b) eq´s, but you can still add loads of high frequencies without getting any harshness. Punchy!
