KHDK Electronics No. 1

A tube-like overdriven amp on your pedalboard

Powered by KHDK's original circuit, the No.1 is designed in the spirit of an overdriven tube amp. Turn the No.1 on and you'll feel like you've switched to a powerful distortion channel on a tube amp.

 Controls
 

GAIN controls the unity gain of the circuit.
VOLUME controls the overall output volume of the No. 1.
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.
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.
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.
FOOTSWITCH engages your No. 1 to “on” or True bypass mode.
