I'm using ISP Stealth into an Avatar with Classic G12H 75th ann and G12 Vintage 30 25th ann and it's stunningly nice.
(but I'm such an MBritt profile slut I can put them into an iPod earbud and bliss out, lol, so don't listen to me)
I love my Stealth but I still want tube power. I am very anxious for Fryette to release the LXII...
