I have a Shuttle 3.0 1x10 combo that I really like. It's all the volume I need for gigs without PA and plenty as a stage monitor with PA/Monitors. I have a Modulus Q5 - fantastic bass. My current set up is very clean. Sometimes I'd like it just a little "warmer" for lack of better term. Not distorted, or overdriven, just warm. There is a nice Genz Benz Shuttle 6.0-210 combo at the local store. The tube pre in the Shuttle is nice. I don't NEED all the power, the 2x10 is a little beefier than my 1x10. A 2nd option wold be to get a tube DI to use in front of my amp, and for gigs where I don't use a stage amp - like at church. I'm thinking that the Demeter would be a good one. Thoughts and comments welcome.
