Lurker here, first post. Look, I'm not really much of a guitar player. But I've been doing rhythm work for a praise band with the neck pickup on my MIM Tele and a DRRI I originally bought for lap steel. As of a few weeks ago I was all the music they had. But now a few more musicians are coming together and we're getting the PA sorted and working correctly again. Although the DRRI is probably plenty loud enough to part everybody's hair, I agree it needs to go into the house mix with everything else, for monitors at the very least. I like my amp and it's tones and want to keep using it. Rather than mic'ing it I thought maybe a Red Box would be a good or good enough solution. I know it goes between the amp and the speaker. My question is whether I could just connect it to Ext. Speaker as a simpler solution? Is that going to mess with the load/impedance of the internal speaker? I'm not married to this approach and doing it the "proper" way is fine, I'm just curious. I know there seems to be a lot of confusion or ignorance about the proper (and rather limited) usage of Ext. Speaker on these amps.
