We wanted a new speaker that was in between the British Sound and the American Vintage sound so we came up with the new Greyhound Speaker. During the design process we mainly used a Blackface Twin to test so we think this speaker sounds particularly good in this type of amp. As far as tone goes, the Greyhound is a bit brighter than a Celestion Vintage 30 but has more punch than a Jensen C12N. It has a great rock tone but stays clean enough for those who don't like too much speaker break-up.
