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.
Strung Out's latest album, Agents Of The Underground, is not only their 7th full length, but it also marks the band's 20th anniversary and is a true testament to their relevance and longevity. Think about it: two decades. Two decades in the underground with thousands of live shows, tours on five (5!) different continents, over a million records sold hellip and they've managed to do it all while on an independent record label. More striking than their massive sales, which is a notable for any artist in this day and age, but the fact that the band that has never had help from "the industry" . They may not have household name status, but they do have a colossal worldwide following and a loyal fan base that has been with them since the very start. Such is Strung Out's true legacy: devotion to the music, devotion to the band, and devotion to the fans.View Artists Profile
