I might be going to Dougs Tubes today as he is my area on NY. He has a lot and everyone raves about him

Just dont know which ones or brands to get for my 20/20. Looking for super cleans and not too gainy Metallica (late metallica live) crunch. More depth and note articulation, not overly saturated Lamb of God and all that other harder stuff(not my bag)
Doug has a good reputation and he certainly has tubes that are to mesa spec. Just remember that you can do alot more with eq than with a tube change, unless the tubes are bad.
yeah for sure my man. Just when I get a used power amp, I don;t know where it has been, how long have the tubes been used,life of them etc. So I like new tubes for used amps
