G12H30's are "replicas" of G12H30's from the 60's and 70's. As you can see in one of my previous posts there were originally 2 versions of the G12H30. I believe they were one of, if not the first Celestions with a heavier ceramic magnet. This allowed them to have more control, and power handling, for low frequencies. That is in comparison to the G12M20 or "greenback", which was the standard Celestion of the day. The Vintage 30 was supposed to be a greenback, with higher power handling. IMHO the vintage 30 sounds much better than the greenback, but it does inhabit the same frequency range, and has a lot of the same midrange character, and bite. Greenback's, Blue's and Vintage 30's all have most of what guitarists are looking for in a guitar speaker, except for tight bass and low mids. That is why all the boutique companies are mixing speakers these days, and trying to get the best of both worlds.
