Electronic Audio Experiments Hypersleep

The Electronic Audio Experiments Hypersleep is an analog reverb. But – some may say – “don’t you need springs to make an analog reverb?” Well, not if you are after something that’s not necessarily vintage-sounding or realistic.

The Hypersleep is based on the unusual MN3011 bucket-brigade device, obsolete to the point of being cool again, just like 8-bit music. It works like this:

The MN3011 uses an array of staggered delay outputs to produce a smeared-out echo. Feeding this echo back upon itself produces a reverberant texture.

The pedal also features a modulation circuit to add extra character or wavey motion.

The Electronic Audio Experiments Hypersleep is probably not the right reverb for those looking for realistic space emulator, but the niche of character seekers should find something quite unique in this device.

Synth demo below:

The Electronic Audio Experiments Hypersleep is a solid-state analog reverberator. It evokes the immediate acoustic reflections of metal and tile, but with a darker timbre and a ringing, fluttering decay—forgoing epic atmospherics in favor of liminality.

At the heart of the Hypersleep is the unusual and obsolete MN3011 bucket brigade device. Unlike other BBDs with one input and one output, the MN3011 uses an array of staggered delay outputs to produce a smeared-out echo. Feeding this echo back upon itself produces a reverberant texture. The reverb length can be modulated via the onboard LFO for atypical chorus and vibrato effects, or the haunting sound of a room changing size in real time. As always, careful signal conditioning ensures that Hypersleep is friendly to any instrument or line level signal source.

Controls:

  • Level – overall effect level, gracefully overloads at higher settings

  • Space – delay time of the BBD, simultaneously controlling six taps on a single delay line

  • Mix – blend of clean and effected signals, from full dry to full wet

  • Feedback – increases the decay time of the reverb, will self-oscillate at extreme settings

  • Rate – modulation rate, from imperceptibly slow to nearly audio rates

  • Depth – modulation depth, from subtle vibrato to warped pitch bending

Additional features include buffered bypass soft-touch relay switching, 9V center negative power (180mA current draw), top-mounted jacks.

All Hypersleep units carry a lifetime warranty tied to the original owner.
