The Keris is a asymmetric blade, infused with the spirit of frustration and inspired by the sounds of perforation. The external control of The Keris will increase both shrillness and volume. There is no tone control. Two interior controls exist to aid with synchronicity between wielder and weapon: DIP Switch On: Asymmetric clipping diodes in-circuit. This is the default setting. DIP Switch Off: Clipping diodes removed. A louder, trashier distortion with strange buzzing note decay. Gain: Turn to increase or decrease gain. Set low as default. High output pickups may benefit from lowering the gain further. Exploring the limits of this control may result in unintended outcomes; both "good" and "bad". -- Bypass: True Bypass Power: 9VDC, 2.1mm centre-negative barrel Power consumption: not a lot Running this unit off of an isolated power supply is highly recommended.
