I am the original owner and have had this stored away in my home for a good number of years. I no longer have any way to test to see if it is fully working so I am selling it for parts. I was able to plug a Mic into it and the EQ light levels responded to the change of my voice. That is as far as I know. Thanks for looking!

Yamaha Equalizer. My father was the original purchaser of this. It was then passed to my brother. It hasnt been used in years, however I did a days worth of testing on a McIntosh system and it worked well. Very good price on this. Please look at all the photos in which you can plainly see all the lights work. Will be boxed with foam and seriously packaged. Thanks for looking

Well, Ive owned this for many, many years. However, its time to pass this awesome EQ on to someone who will use and enjoy it now. It does have some scuffs and scratches over the years (see photos). All the sliders work, and all the lights work. Went over it one last time and cleaned all the sliders with deoxit fader cleaner. Any questions just ask. EQ only, no accessories. Thanks, and check out my other listings for more great items!
