This ambient machine was designed to cover anything from typical reverb – delay to outerspace exploration.

The Sputnik is reverb-delay hybrid that achieves amplitude(tremolo) and pitch modulated reverb without the use of algorithms and  microcontrollers but only solid state devices: the BTDR-2H reverb brick and PT2399 delay chip. It features a Reverb and a Delay channel that work in parallel and can be mixed together in mono or sent to separate outputs for huge stereo ambience.

Each channel has its own unique modulation circuit with triangle, square and random waveforms that offers a huge range of subtle slow fluctuations to ring mod pitch and amplitude modulation. If that doesn’t cover your tinkering needs, you can add external effects to each channel via the dedicated fx loop jacks. The Sputnik also features a momentary footswitch for infinite feedback, a tails footswitch and a dry kill toggle.
