Well I wish I could give you guys an informed mini review on this buffer, but it's still sitting in customs in Seattle(4 days now).
I do however have the new tubes(JAN-GE 5654W and Mullard CV4010)all ready to go.
To go along with what Alan said. A guy here in the office plays the guitar and has a very nice Peavy tube amp that uses the KT77 JJ tubes from Eurotubes. Very cool sound.
