USED Keeley Katana Clean Boost ***RARE***

This is one of the rarest of the Keeley Clean Boosts we've seen. While we've ran across a few similar, they have had a different knob. This one seems to be unique, and with the white knob, was different than any of the other Keeley's of the period.  This pedal was never sold but was used on a pedal display in our store. It has sense been sitting in its box for several years as we've added locations and closed locations, shuffling inventory around, then the pandemic, blah, blah.... This was manufactured in 2014. Serial Number K8879. To date, we have not found any other pics online of this pedal with the specific boost knob combination.  Two modes, Pure Clean and High Gain 1. With the speed knob Pushed In, think of it as a volume control that goes to 20. 2. With the speed knob Pulled Out, it's a cutting boost with a bit of gain. Not quite an overdrive, just overdriven tube grit and edge to your tone. Dual FETs for the most tube-like tone in a transistor design. Power Doubling on the inside so you put 9VDC in, and we use a charge pump to nearly double operating voltage! (Caution 9 Volt DC Maximum Input Voltage (don't try to put 18 volts to the unit hoping that the doubler will make it 36VDC!) What do higher power supply voltage rails mean?! -> SUPER CLEAN HIGH-HEADROOM BOOST! Pull the Level knob out to switch -> Tube-like gain! THE EDGE!!!!
