I have a 1980 or 81 Fender Bassman 135 head that I picked up recently and it's in extremely good condition. I talked to a couple of folks about the ohm load for the cabinet - the head has two 4 ohm speaker jacks out. I've been told that I can run two 4 ohm cabinets - one out of each 4 ohm jack for basically a 2 ohm load. Since I have a couple of 4 ohm cabinets, this scenario would be great. I've also been told that I would actually need to run an 8 ohm cabinet out of each jack for a total 4 ohm load rather than hooking up the 4 ohm cabinets. Is anybody familiar with the Bassman 135 head that can clarify if I could in fact run two 4 ohm cabs out of this head? Thanks.
