The sum of my experience with Creambacks is my Rivera Thirty Twelve combo. I have never been completely happy with a combo amp before. To me, they're always a major compromise. But this amp with this 65 watt Creamback is so good. It sounds so thick, middy, and creamy. In my experience, combos are usually mid heavy, but the mids always sound boxy and strident. I'm not sure how mush is the amp, and how much is the speaker, but I'd be interested to try this speaker with other combo amps to see what it does.
