Changing tubes...easy right? In this case, not so much. In this video we'll show how to change those 6021 JAN Philips subminiature tubes in a Seymour Duncan SFX-03 Twin Tube Classic guitar overdrive pedal. The owner of this pedal was complaining of possible microphonic tubes and poor sound quality, so this will give us a unique opportunity to check out the guts of this pedal and follow the process of re-tubing it.
BONUS!!!! At the end of the video, stick around to see a totally random clip of Showbiz Pizza Place animatronics - Billy Bob and Co. - at the 2015 Kentucky State Fair! Why? Just because.
