    Good condition Blue Tube 903 real tube preamp/overdrive pedal handbuilt by John Kallas. A big, awesome feature of his version of the Blue Tube is that it will run off of standard center-negative pedal power (as opposed to the original that had it's own plug built in), making it more pedalboard-friendly. Comes with a GE JAN 5157 (12ax7) tube for mild to gnarly natural tube drive. I have also used a 12au7 to get more headroom and run it as a tube preamp to warm up a solid state head. This is one of his first 903 builds in the funky cool box that's shaped like the original.

    $135 shipped CONUS SOLD
