I purchased a used Avatar 2x12 cab that came loaded with two of these Celestion G12H Anniversary speakers. It wasn't until I began focusing more on tone did I realize what a gift it was to have these in my cabinet. These speakers are described by Celestion as a mix between the vintage style Celestion G12M greenback speakers, typically found in new Vox AC30s and some Marshall cabinets, and Celestion V30, found in Mesa, Orange cabinets. I found that I can pair almost any head with this cabinet and get a great tone out of it. They are responsive and clear, similar to the V30, but have the nice vintage voiced back of the Greenbacks. I have a Mesa 4x12 cab loaded with V30s and I favor this cab over that. The cleans are very chimey like you would expect from a Vox, but does not get shrill when you crank up your gain.
