The Kink Guitar Pedals Atomic Spaghetti is an overdrive/tremolo. It's based on the sought after Hermida Audio Zendrive played into an optical tremolo.
The Atomic Spaghetti features one side for overdrive controls and one side for tremolo controls, plus an internal trimpot for overall volume.
Atomic Spaghetti Overdrive
The overdrive sounds absolutely fantastic on its own, but add in the Tremolo circuit and you can get a wide array of deep, modulating drive tones. Like the Zendrive it's based on, an internal trimpot allows you to adjust the voicing for subtle changes in character.
Atomic Spaghetti Tremolo
The optical tremolo is wide ranging, taking you from slow pulses to frantic, stacatto-like jabs with a twist of the Rate and Depth controls. Adjust the character using the Waveform control.
