Many folks who buy our tubes know that we use a special process to categorically rate our tubes so that players can select the tubes that best fit their preferred tones and styles. However, we get a lot of questions about our rating system, and what the numbers actually mean.
IMPORTANT BIAS NOTE: If you're replacing a tube with the SAME TYPE of Groove Tube (tube model and rating), you do not have to rebias your amp. In any other case, you should always have a qualified amp tech reset your amp’s bias whenever changing your tube type or rating number.
At the age of 12 I got my start by picking up my fathers bass playing 60'S music i had taught myself . At 14 I was given the album Dookie (Green Day) by a student teacher in my 7th grade science class. Mike Dirnt became my biggest influence mentor and At that moment I knew I wanted to be a bass player in a rock band and tour the world. After a decade of touring in independent punk rock, rock, and pop projects I got an opportunity to step in on Bass for Falling In Reverse in Jan 2012.View Artists Profile
