Hey!
I just bought a used OTS Mini 20 lunchbox head.
I play in a pretty loud rock situation. (think: Cream, Blind Faith, Mountain, The Doors, etc..)
I have a nice vertical 2x12 and a 1x12 with Scumback speakers.
I have played my 18w Tweed Deluxe in this situation and it could get over the bass and drums but it was pretty much dimed (and muddy)
I have played my Fuchs Blackjack 21 combo with this band and the volume was at about 2oc. Even though the Fuchs is really great and very much like the OTS 20, I suspect that I'm going to like the OTS 20 better and I can play it with either my 1x12 or 2x12 cabs.

I'm sure that it will sound fantastic but I'm wondering how well it cut.

I'm wondering if anyone here has played their OTS 20 in a rock band situation with success?
