Here's a clip of what I believe to be a 1969 LPB-1, that I purchased from Action Music in Falls Church, Va. Using a 2016 Fender Jazzmaster and Orange Micro Dark purchased from Melodee Music in Sterling, Va. The Micro Dark is being fed to a Marshall cab with Greenbacks. The video also features a 1979 Big Muff Pi V5 Op Amp with Tone Bypass, purchased from Action Music. This thing is so far beyond awesome, but very finicky and strange. As you may be able to see in the clip, there is an attached 1/4" tip on the amplifier side which comes out of the right side. I attached a female adapter to use a longer cable instead of plugging directly into the amp. The signal flows from left to right which makes it tough to stick on a pedalboard. They were designed to stick directly into a clean vintage amplifier to add some drive.
