Hey,guys. Just picked up 2 of these vintage Fender 2x15 unloaded Cabs yesterday for $75.00 apiece. Sold to me as Bassman cabs,but may or may not be. My question is,were Bassman or any other 2x15 cabs from the 60's or so, equipped with horns? Both baffle boards have spaces for horns,and appear to be factory since the speaker holes are offset from the middle. Any ideas? Thanks!
