MANUAL v1.0

The Lightkeeper is a tube based, all-analog boost/overdrive pedal, 
designed to deliver that ‘tube-feel’ to any amp, house system, or 
recording interface. Inspired by Dumble’s legendary clean channel 
sound with lush dynamics and touch-sensitive sound we crave. It’s a 
portable tone palette that’s perfect for enchancing  the flat-sounding 
amps or tucking in your case for jam sessions.
Sculpt your base tone from crisp clean to an edge of breakup while 
reserving the footswitch boost/mid-punch for solos, thanks to the 
3-way Mid and Boost footswitchable controls.
The Lightkeeper operates as a pure analog, Class A audio pre-amp 
offering high fidelity sound without semi-conductor or DSP in the 
signal path. It features a genuine ECC83/12AX7 vacuum tube operating 
at 250VDC high voltage and delivers a warm, rich tone with gentle and 
natural compression.
