This is something that I don't even know about, but I thought I'd ask everyone here. I have this old Fender Bassman head, but my 4-ohm cabinet has gone to Fender heaven, so now I've got a 1x15 8-ohm cabinet. I just don't like the way it sounds (I took one of the speakers from the original cab) running at 8 ohms. I'm torn between trying to get a new 2x15 4-ohm cab, but I don't want to shell out the money (could be touchy here right now...you know what I mean!), so I got to thinking. Does anyone market something that can be plugged into my other speaker jack to bring the amp down to 4 ohms without adding another speaker? I mean, we're talking about a resistor soldered onto a 1/4" jack, right? Anyone got anything that could help me?
