cool..thanks!I love the vintage greens I have in my 4/12 MArshall cab from 1974-perrrfect with the 50 watt marsh head...but, I have started running my boogie mark IV in stereo, and the greenies get a little flubby-dubby-gonna pull them , keeep them, and insert v30s for the added pwer capability..if i need the greenbacks, I can just swap out..thinking about running 2 greens and 2 v30's...hmmmmmm..man, this stuff can keep a man busy!!
