Vintage JBL E120 with original cone in custom-made, original ported cab.
I bought this from a guy who studied at Berklee in the late 70's/early 80's. He said he had the cabinets made for him by a company that made professional music equipment. He used this in a rig with a twin reverb and an Altec in a matching cab.
Has the classic later Jerry Garcia sound, perfect for getting those Grateful Dead lead sounds.
