Hello, Our drummer brought me a bass cabinet to use after my old cabinet and amp became worthless. He refers to this cabinet as a road cabinet. It requires 1 - 15" speaker, is ported, and is rather large. I would like to know something about this cabinet because it has awesome tone. He doesn't know the manufacturer because it is old, possibly from the 60's or early 70's. I realize this is vague, and I don't have a picture as of now. Any help with identification would be appreciated.
