I love my GB12 and Private Jacks. Both are obviously "Greenback" styled. I'm looking to get some Wizards and maybe a Texas Heat to try out. I also love my old Celestion G12-65. I didn't think the Tone Spotter quite nailed the same tone. Could have been a break in thing.
I have tried the Cannibas, it's good. Uh maybe I should clarify, the speaker sounded good. 8) The Swamp Thang was cool, but a very distinctive tone. You have to commit to it. It reminded me of the Billy Gibbons, Tejas era tone. Kinda funky in agood way, not exactly where I want to hang my hat though. What a cool line of speakers they have to choose from though, quite versatile and you will find what you are looking for and most importantly, they didn't SELL OUT and have them made in China. What is Celestion thinking anyway?
