This is a really cool old EQ pedal made in the 80s by Maxon Japan. Just setting it flat (or a little mid bump) and using the level control as a clean boost adds such a cool vibe and feel. It’s the not the most quiet eq pedal when you start really pushing the faders out from center but this is the least noisy one from this series that I’ve owned. It’s also in as good of condition as you’re ever going to find as they didn’t use quite as good a paint as the Boss pedals from this time And they look whipped if they weren’t babied.
Thanks for looking!
