I have a Fender Bassman 70 head in great shape: looks good and sound better. Currently I'm playing it thru a 4 ohm Peavey cab which has a 15 *AND* 2 tens in it. SO as you could imagine, this cabinet is pretty bulky and heavy. I want to get rid of this cabinet, but I don't want to lose that sound of a 115 and 210. I don't know much about this head, so my question(s) may be overly basic. Can this head drive two cabs? Specifically, are there 2 plugs on the back? I see an "ext. Speaker" jack, but is this the 2nd cab spot? Also, the head says it needs 4 ohms, so If i buy two 8 ohm cabs the net load will be 4 ohms, right? SO this will be okay? or is the head expecting 4 ohms per jack? Lastly, does any one have experience doing this with a bassman? And do you have suggestions on which cabs to buy? I'm looking to spend around $300-500 per cabinet.
