What is tube rolling?
Top of Page A: “Tube rolling” is a term used to describe when a person decides to alter the sound of a tube amplifier by changing the output tube to a different type/version on the premise that various tube types “sound” different. The premise is based on the idea that each different tube type has a different electrical characteristic and that by testing various tube types, you will find the “magic one” that will make the amplifier sound the best. Unfortunately, this “idea” stems from experiences people have with “typical” tube amplifiers. Because the TubeDriver BLUE amplifiers employ the patented TubeDriver BLUE circuitry, tube rolling is neither necessary nor desired. The patented TubeDriver BLUE circuitry delivers the “live stage” and “recording studio” sound via the thermionic emissions of the tube rather than the overload characteristics of the tube, like typical tube amplifiers. The 6SL7GT twin-triode tube was specifically selected for it’s thermionic/emissive qualities and is an
