Hand-built and personally autograph by BK Butler on a limited number every week.

Be careful, not all BK Tube Drivers listed for sale are hand-made by the man who created it and they will be cheaper than this one.

According to BK, the design and sound is the same as the original (as supplied to Eric Johnson, David Gilmour, etc) but with improved parts such as Switchcraft all metal jacks, click pots, etc.

Each unit is hand built to BK’s specs and he personally checks out each Tube Driver to perfection. He engraves his signature on the bottom of the case (see picture of the one I'm selling with the serial #). This insures authenticity. I bought this unit directly from BK. Please go to his site for details at "butleraudio" dot com. 

This tube has been changed to a JJ Electronic 12AU7/ECC82 tube, but I will send you the original 12AX7 that came originally installed by BK. See Gilmourish’s comment about the 12AU7 characteristics (google "gilmourish 12AU7").
