Lush, Majestic Reverbs. Insane DSP Power.

The philosophy behind our blueSky Reverberator is simple—take a ridiculously powerful SHARC DSP and dedicate it to doing one thing only: producing the most lush, majestic and stunning reverbs ever. Many hours and sleepless nights in the Strymon sound design labs were devoted to developing the complex reverb algorithms found inside blueSky. We squeezed every last drop of processing power available.

blueSky Reverberator - Reverb Pedal

Prepare for Reverb Bliss.

Whether you’re a classic spring reverb fan or a studio rack aficionado, you’ll find your mojo here. blueSky provides three different reverb types, each with three modes, for a total of nine completely unique reverb experiences. blueSky even delivers an extremely versatile plate reverb, a rarity for a stompbox pedal. A full pre-delay and damping section provide deep reverb tone shaping. Add the mod and shimmer modes and you’re in store for unending reverb bliss. Couple that with 24-bit 96kHz converters and 115dB typical signal to noise, blueSky is equally at home on top of a studio console as it is in front of a tube amp.

    • Bright Spring
      A bright spring with no pre-delay and a moderately heavy mix recreates a miked up amps' spring tank for some classic surf.
    • Plate Showcase
      A variety of settings using the plate algorithm showcase the versatility, including a bright ambience (at 0:07), a large synthesized bright room (0:17), a larger bright metallic reverb (0:27), a couple of beautifully damped dark plates (0:45), a 'huge rubber barrel' that has maximum low and minimum high (1:01), and finally a cymbal-like plate with minimum low and maximum high (1:22)
    • Modulation
      The 'mod' option for the plate algorithm creates a beautifully chorused effect when mixed in with the dry signal. This clip uses some pre-delay to prevent the dry signal from being overwhelmed, and to allow the sound to 'breathe'.
    • Plate Shimmer
      The plate's 'shimmer' effect generates octaves within the tank to create an ever-expanding and regenerating bloom of pure harmonics that adds an ethereal synth-pad type of effect.
    • Room Showcase
      The quality and range of the Room algorithm is highlighted with an array of sounds, including a lively walk-in closet (0:04), a nicely balanced room (0:15), a warm, small auditorium (0:28), a large hall with a long, balanced decay (0:41), an empty arena with lots of bass-traps but no high damping (0:57), and that same arena with plenty of high-damping but no bass traps (1:12).

Reverb Types

  • Modes
  • Types
  • blueSky Reverb Modes

    Normal mode provides an unmodified version of the selected reverb type.

    Mod mode adds gorgeous modulation to the selected reverb type.

    Shimmer mode adds regenerative pitch shifting “in the tank” for a reverb trail that rises into the clouds. With the Plate type, pitch shifting is octave-up. With Room and Spring types, pitch shifting is an octave plus a fifth.

    Plate is an intensely high quality vintage studio plate reverb.

    Room is a versatile room ranging in size from a small bedroom to a massive arena, depending on where you have your Decay, Mix and Pre-Delay set.

    Spring is an excellent recreation of the best spring reverbs we’ve found.

  • Front Panel Controls
  • Ins & Outs
  • Decay controls the decay time of the reverberated signal. Set low for small rooms, plates and short springs. Set high for huge arenas, massive plates and enormous springs.
    Mix controls the balance of your analog dry signal and your wet signal, from 100% dry at minimum to 100% wet at maximum. The mix occurs entirely in analog. 50/50 mix occurs when the Mix knob is set to 3:00.

    Hold Tap and Bypass simultaneously while turning the Mix knob to access the +/-3dB Boost/Cut feature. Achieve a plus or minus 3dB boost or cut when the pedal is engaged.
    Low Damp controls the amount of low damping in the reverberated signal. Turn counter-clockwise to reduce the amount of low end in the reverb decay trail.
    Pre-Delay controls the delay time before the reverberated signal appears. This is an essential control in creating an accurate and pleasing reverb.
    High Damp controls the amount of high damping in the reverberated signal. Turn counter-clockwise to reduce the amount of high end in the reverb decay trail.

  • exquisitely designed, painstakingly constructed reverb box that can hold its own against some of the finest rack units. A spacious, shimmering five stars out of five for what I firmly believe to be the best reverb pedal on the market.
