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!
- 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)!
- 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.
- Gain – Turn CW for more distortion and sustain
- Tone – Rotate clockwise to emphasize mids and highs
- Level – Turn CW to increase output level (dB)
