Great tubes from a great company

by Tim Moran from McHenry, IL
February 1, 2012
Music Background: Hobyist.
Id like to know how the person claiming that these tubes arent matched tested their tubes to prove that they werent. If you have that kind of equipment you dont buy all ready matched tubes. I smell... read more [+] some BS brewing in that persons coffee pot. Thes tubes are great. They are rich and full of detail. They actually have a lot more chime and presence than JJ 6l6's in my opinion. And for mesa to use them knowing they are chinese I think speaks volumes about them. Mesa isnt a fan of china. They wont even use the chinese V30 speakers. To me that says alot. close [-]

They're the only one's I'll trust in my Nomad Head, Combo, and F50 Combo.

Same price and Free ship make this a no-brainer!

Not Matched

Music Background:
These "matched" 6L6 tubes were not even close to being matched. Very poor quality.
