Amen to that! Although my Streamliner gives mine a good run for its money.
Playing out the B-15 wouldn't be the worst idea IMO. Especially with an 8 ohm extension cab. Don't you have an Ampeg 1-15? If the club is small the guitar players shouldn't be using anything bigger than a Deluxe IMO. The audience would definitely appreciate it.
Good luck with the Marshall!
Well, I love the Mesa cabs I have. They sound good with anything IMHO. I also added an Orange Terror 1000 (I wanted to have a solid state backup amp; I also wanted a 500 not a 1000, but I took what they had in stock!) to my collection and it sounds great through the Mesas. The attack issue and woofiness of the Prodigy is gone and the cabs put out a nice bassy response that's clear in the mix. I could try the B-15 head with one of the Mesa cabs, they're 8 ohm. I just like to have enough wattage for lots o' headroom and not overdrive the amp too much. Might do that on Wednesday.
The Marshall shipped today so I might have it by Wednesday, we'll see!
