I have a JBL 520c, asking $130, Or Best Offer, Shipped. It's in great condition other than a slight peeling on the bottom right corner of the face. It's also got a little bit of dust still on it from sitting, I'll do my best to have it all off before shipping. I'm getting out of the hobby for a bit, so I'm narrowing down my collection.
Not looking for anything specific on trades so feel free to make an offer.
