Secrets of the Crate Blue Voodoo...or is it BLUE DOODOO? You Decide!

Today we have a 1995 Crate Blue Voodoo BV-60 combo in for repair. Some techs and players call these the "Blue Doodoo". This will be the first one I've had in for repair on the channel. We'll open it up and troubleshoot for no sound at the output. We'll also examine the construction and the circuit and see if the nickname "Blue Doodoo" is justified. We'll also examine the automatic bias or "self bias" circuit that is an interesting feature of these early Blue Voodoos and compare to a later Version 2 bias circuit with the adjustable bias pot. An easy way to tell which version you have is to turn the amp around, and if you see a "Hum Balance" control on the back, you have an early auto-bias version of the amp. At the end, we'll demo it with my Fender Tele.
