K818 Dual Overdrive

Two Iconic Overdrives in One!

The ultimate hybrid? Only you can be the judge.

The K818 is a dual overdrive preamp bred through and through with classic K-Style and OD-808

DNA. With a wide dynamic range, sweet overdrive, and lowered noise floor, the K818 is well

suited to cover a variety of playing styles and genres; most notably blues-rock!

Notable Features

  • Boosted internal power supply with 30 volts of dynamic headroom (+/- 15V)
  • Two mechanically isolated channels
  • Transparent buffered input/output
  • Soft clipping overdrive
  • Lowered noise floor
  • Series channel stacking with smooth overdrive and sustain

K-Style (Channel #1 = right side)

Legendary K-Style tone with lowered noise floor and softer dynamic clipping. Don’t be afraid to

crank the gain pot fully clockwise (CW)!

CONTROLS

  • Gain – Turn CW for symmetrical soft clipping
  • Treble – Classic K-Style treble boost
  • Output – Turn CW to increase output level (dB)

818 (Channel #2 = left side)

Classic OD-808 tone with crunchy overdrive, wider dynamic range, and increased output level.

Feel the difference that 30V of headroom delivers vs a standard 9V supply.

CONTROLS

  • Tone – Rotate clockwise to emphasize mids and highs
  • Level – Turn CW to increase output level (dB)
