Two modes, Pure Clean and High Gain

• With the speedo knob Pushed In, think of it as a volume control that goes to 20.
• With the speedo 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.

FEATURES:

• 9 volt DC jack or Battery operation. DC jack at top of unit like Boss or Ibanez effects.
• Internal Power Supply Boost - turns your 9 volts into 18!!! The power supply's high voltage is what leads to this super clean headroom pre-amp.
• JFET design - clean tones, tube like when they overdrive or clip.
• 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! What does that mean?! Switch in -> SUPER CLEAN HIGH-HEADROOM BOOST! Pull the switch -> Tube-like gain! THE EDGE!
• Push-Pull Speedo Knob. Gain controlled by side mount knob so it can be adjust with your feet. Pull out the Speedo Knob for saturated higher gain tones.
• Metal Film Resistors and Caps. Ultra Low Noise Design.
• Blue LED, a Keeley Trademark!
• Silver soldered and teflon coated wire
• True-Bypass
• Battery or DC adapter powered
• 5 Year Warranty
