CONTROLS
1. Gain Controls the unity gain of the circuit.
2. Volume Controls the overall output volume of the No. 1.
3. The hi/lo switch is tied directly into the gain. The lo setting offers a warm, tube-like boost and a subtle crunchy overdrive, great for rhythm playing. The hi setting adds saturation, sustain, low end and compression. This setting is recommended for a more powerful rhythm or soloing.
4. Bass Controls the bass and lower mid-frequency gain. The bass is tied into the gain, making it a secondary gain control and enhancing your low end.
5. Treble Control Is a passive, natural sounding low-pass filter. It cuts high end and offers a wide frequency range. Turned clockwise, it becomes raw, aggressive and cuts through. Turned counterclockwise, it cuts highs for a more mellow and warm tone.
6. Footswitch Engages your No. 1 to “on” or True bypass mode.
POWER
The KHDK No.1 Overdrive is powered by a single 9V battery. You can access the battery connection by unscrewing the bottom plate of the pedal enclosure. Alternatively, plug in an external 9V DC (center negative) power supply.
