Tape: The First Effect

Our journey begins with the early recording studios of the ’50s and ’60s. The introduction of reel-to-reel tape machines and the creative engineers that used them brought on some of the fattest sounds imaginable. These early machines really were the first effect pedals—they just wouldn’t have fit on your pedalboard!

From the inherent warmth and luscious tape saturation—to the forgotten art of how these machines were manipulated—they are capable of creating a huge range of beautiful, distinctive, and enveloping sounds.


Deco - with studio tape machines

Mid-Century Maverick.

Deco brings this original inspiration back, giving you these vintage tape effects from the earliest recording studios, right on your pedalboard.

Deco’s Tape Saturation smooths out your sound with familiar and delicious tape compression and saturation, while fattening it with subtle tape-driven transparent overdrive. The Doubletracker provides the power to shift your sound in many ways, easily allowing you to achieve syrupy slapback tape echoes, psychedelic tape flanging, and gorgeous tape chorusing sounds.

Two Effects in One

Tape Saturation

The “always on” effect.

Give your sound the smooth and warm qualities of analog tape, along with the enhanced touch sensitivity and playing dynamics that are intrinsic to the inner workings of tape machines. Achieve incredible transparency at low levels, with reduced high frequency spikes and a harmonically rich low end. Turn up the Saturation to increase the amount of tape drive, dynamic compression and distortion.


Deco is perfectly suited for a last-in-chain, “always on” sweetening effect. Everything sounds better on tape. Want to push the limits of tape beyond what was originally possible? Use Deco as a tape-style transparent overdrive—crank the Saturation all the way up to “peg the meters” and gently overload the machine’s input.


Fatten your sound with tape.

Go back to the early days of recording studios, where a few creative audio engineers discovered a new world of augmented sound by pushing the limits of studio tape machines. By inventing automatic doubletracking, they introduced echo, flanging, and chorus to the world of recorded music.


Intensify and widen your sound with Deco’s Doubletracker controls. Turn the Lag Time to obtain classic slapback tape echo, spacious doubletrack chorusing, and mind-bending tape flanging. Add random modulation with the Wobble control and go from very subtle movement to more extreme undulations—just like having a recording engineer vary the speed of the machine.

  • Audio Samples

    • It's Alright ○
      A vintage tape slapback effect adds dimension and a cool retro vibe to this fingerpicked ditty. Effect engaged at :04.
    • Strolling ○
      A longer tape delay with mild Wobble creates a beautiful backdrop for some pretty chords. Effect engaged at :06.
    • Calling ●
      Heavier Saturation settings create a bed of harmonics to enhance this rhythmic tape echo in Bounce mode. Effect engaged at :03.
    • Been Workin' ●
      A short tape delay inverts as it bounces off the back wall to add depth to this rhythm.
    • Swamp Echo ○
      Bounce mode creates a two-echo room sound for this baritone riffing. The Tape Saturation provides just enough grit for the proper attitude. Effect engaged at :04.
    • Landscape ○
      A generous amount of Wobble in Bounce mode gives two repeats that play off each other and fill the soundscape.
    • Sun ●
      A 50/50 Blend creates a classic slap that's enhanced by some adding Wobble on the Lag Deck. The Saturation fattens up the tone further.
    • Staccato Space ●
      Maximum Lag Time results in a long tape echo. The Blend knob is set to favor the Reference deck signal over the echoes of the Lag deck.
    • Stereo Images ●
      Wide Stereo Mode splits the Refernce and Lag decks to the Left and Right channels respectively for a beautiful stereo image. Effect engaged at :08.
    • Air Between ●
      An expansive tone is created by combining some Tape Saturation with maximum Lag Time and Wobble in Bounce mode. Effect engaged at :05.

  • Audio Samples

    • Thick Shake ●
      The Lag deck is heavily wobbled with a very short Lag time to create a phasey experience. The Bounce setting creates a thicker effect.
    • Flange Filtered ●
      A distorted signal is manually flanged for static filter effects by varying the Lag time with the Wobble turned down. Effect engaged at :04. Lag Time starts at 50%, is reduced at :13, and again at :23.
    • Off-Center ●
      Turning Blend to just the Lag deck creates a pitch-bent signal with heavy Wobble. Blending in the Reference deck creates a wild tape flange. Bounce mode creates a stereo panning effect as the Lag deck wobbles around zero lag. Effect engaged at :03.
    • Vintage Doubles ●
      Maximum Wobble pairs with a longer Lag time to create a pitchy double-tracked tape chorus. Effect engaged at :06.
    • Harmonics ●
      A wide double-tracked tape chorus is achieved with a moderate Lag setting and some Wobble with the Bounce setting. Turning up the Saturation adds rich harmonics. Effect engaged at :04. MXR Distortion Plus used before Deco.
    • Saturated Burst ●
      Tape Saturation adds fullness and overdriven harmonics. Effect engaged at :04. Lag Deck is blended in at :13 to create another level of richness.
    • Rocking Chair ○
      This doubling tape chorus uses a moderate Lag Time setting, wide Wobble, and a lower Blend for a milder effect. Effect engaged at :08.
    • Space Blues ○
      A short Lag Time and mild Wobble create a tape flanger that brushes the through-zero point but doesn't go through. Invert mode creates a signature tonality. Effect engaged at :07.
    • Lagging in Stereo ●
      Wide Stereo Mode splits the Reference and Lag decks to the L and R channels for an expansive stereo field. Tape Saturation adds some mild overdriven harmonics. Effect engaged at :07.
    • Subtle ●
      Effect engaged at :06. At minimum Lag Time, the Lag deck will pass through zero as the deck is slowed by adding some Wobble. At :20, Reducing the Blend makes the effect less intense. MXR Distortion Plus used before Deco.
    • Tape Flange ○
      The press-and-hold Auto-Flange mans the controls to transition seamlessly from any setting into a guided journey through zero time. MXR Distortion Plus used before Deco.

    • Blanket of Blues ○
      This clip highlights the dynamic aspect of Tape Saturation. When engaged and playing softly the effect is barely noticeable—but when digging in the fat harmonics are unmistakeable. Effect engaged at :13.
    • Harmonic Intent ●
      Tape Saturation is engaged at :07 with a mild setting for a transparent effect that is 'felt' more than heard. As the Saturation is increased, the harmonics increase and create a dynamically distorted signal at maximum.
    • Maximum Overdrive ●
      A hot bridge pickup with maximum Tape Saturation results in heavy overdrive. Effect engaged at :06.
    • Volume Changes ●
      Here the guitar's volume control is used to show how the Tape Saturation is transparent with lower level inputs and drives nicely as the volume is increased.
    • Fat Clarity ●
      A double-coil neck pickup drives the Tape Saturation while retaining clarity. Effect engaged at :07.
    • Dig In ●
      A neck pickup riff benefits from the dynamics and heavy harmonics of the full Saturation setting. Effect engaged at :05.
    • Stepping Stone ○
      Tape Saturation responds to playing dynamics without taking over the sound or stepping on the original tone. Effect engaged at :09.

  • Ins & Outs
  • Saturation sets the amount of tape drive by adjusting the preamp gain.

    At low levels, a subtle harmonic enhancement occurs, increasing to dynamic compression and distortion as the knob is turned up.
    Blend sets the relative mix level of the two tape decks.

    Turn lower to blend in more of the 'Reference Deck', which can serve to tame your doubletracking effect.Turn higher to blend in more of the delayed 'Lag Deck'. At 12:00, both decks are equally mixed to the output.
    Lag Time sets the delay offset between the two tape decks. This delay offset between the 'Lag Deck' and the 'Reference Deck' creates a full range of doubletracking tape effects.

    Transition from tape flange on the first half of the knob, to tape chorus, slapback, and then tape echo with a maximum 500mS delay.
    Volume controls the output volume of the reel-to-reel decks.
    Blend Type tailors your doubletracked sound by adjusting internal phase and routing to attain subtle differences in tonality and low-end response.

    Sum – Decks are in phase.
    Invert – 'Lag Deck' is phase-inverted.
    Bounce – Right channel of the 'Lag Deck' is phase-inverted and bounced to the left channel input creating a ping-pong-like stereo effect, or a double-repeat effect when using a mono output.
    Wobble adds a random speed-modulation element to the delayed 'Lag Deck'.

    At lower settings, the variations are mild, covering the speed changes that a recording engineer might use to create time-varying flange effects. At higher settings the variations become more extreme while maintaining a tasteful musicality.
    The Tape Saturation footswitch engages and bypasses Deco's tape saturation effect.
    The Doubletracker footswitch engages and bypasses Deco's doubletracking effect. Press-and-hold to engage the instant Auto-Flange feature.
  • High Trim controls a shelving filter for subtle high frequency tailoring. Full bandwidth at minimum setting.
    Doubletracker Boost/Cut boosts or cuts the Doubletracker effect by up to 3dB to allow for precise level matching. Full boost at Max, unity gain at 12:00.
    Auto-Flange Time sets the sweep time for the press-and-hold Auto-Flange feature. Low settings are faster, and higher settings are slower.
    Low Trim controls a high pass filter for subtle low frequency tailoring. Full bandwidth at minimum setting.
    Wide Stereo Mode generates a wide stereo image. Turn past 12:00 to send Deck 1 to the Left Out and Deck 2 to the Right Out. Disable by turning to left of 12:00. Automatically disabled with mono output.

    Press and hold the Doubletracker Bypass footswitch to achieve a recording studio-inspired through-zero flange effect. This engages a “virtual audio engineer” manning the faders and tape reels to create a smooth and predictable through-zero flange experience on the fly. After releasing the footswitch, the controls are smoothly returned to their previous settings.

  • Wide Stereo Mode

    Wide Stereo Mode

    Deco gives you the option for extremely wide stereo imaging to broaden and intensify the sound of your stereo rig. Wide Stereo Mode sends the mono input (summed if using a stereo input) to the Left channel through the ‘Reference Deck’, and to the right channel via the delayed ‘Lag Deck’ to create an adjustable stereo spread. The Blend control acts like a Pan control by adjusting the relative levels of the two tape decks.

  • Expression Pedal Input

    Expression Pedal Control

    Input allows for the connection of either an expression pedal, external tap, or Favorite switch. Plug in an expression pedal and control any one knob with your foot. Plug in an external tap to tap in your Lag Time. Plug in a Favorite switch to save and recall a favorite preset.

  • Individual Bypass

    Individual Bypass

    Separate bypass footswitches allow you to bypass the Tape Saturation and Doubletracker individually. Your Deco gives you two individual effects in one pedal.

  • TRS Stereo Input

    TRS Stereo Input

    We know that there are some out there that like to run stereo rigs. This is why we’ve added the option of running the input of your Deco in stereo. Flip a jumper inside your pedal, use a TRS splitter cable, and now you’ve got yourself a stereo input.

  • Studio Mode

    Studio Mode

    Your Deco is just at home on top of a mixing console as it is on your pedal board. Add the dynamics and warmth of tape saturation to your recorded tracks. Expand the sound of your synths, drums, and even vocals with the Doubletracker. The optional Studio Mode feature tailors the Saturation range to be best suited for hotter input signals. Use with DAWs, mixer inserts, line level synths, or hot effects loops in guitar rigs.
