I've not played a Line 6 but I have a Tiny Terror and I love it. I'm not going to go nuts here, but it's a good valve amp for the money in my opinion. I run mine through an Orange 1x12 which is Asian built with a Celestion GH something K 100W speaker.
This sucker is quite loud! Even on 7 watts. Perhaps look for a cab with a lower db rated speaker? This will bring the overall volume down a little. Or better yet get an attenuator, this is not a cheap option I will admit, and I didn't get one for the TT. But when I did get one I played the TT cranked through it and it did really well.
One thing to note, the TT does not have a clean channel, you can back the gain right off, and crank the volume full bore to get close, but it's never completely clean.
Definately make sure you play one before you buy, I personally think that Orange have a great sound (I own 2) but it's not for everyone I'm sure.
Let us know how you get on!
