Ola dBucket Chorus & Vibrato – Chorus Pedal – Strymon


Certified Organic.

When we set out to design Ola dBucket Chorus and Vibrato, we knew that we wanted to take a high-performance SHARC DSP and dedicate all of it’s horsepower to doing one thing—providing the most lush and organic chorus and vibrato sounds ever heard.

Ola dBucket Chorus & Vibrato

Chorus & Vibrato Workhorse.

Our hand-crafted, processor-intense dBucket algorithm delivers all of the warmth and sonic complexities of analog choruses and vibratos.

Couple that with true bypass, a favorite preset, stereo input and output, and a super high quality analog front end and output section, and you have yourself a versatile chorus and vibrato workhorse.

  • Normal Mode
  • Ramp & Envelope Modes
  • Ola and El Capistan Video
  • Audio Samples

    • Slow and Wide

      This clip starts with Ola in true bypass, and then employs the 'even-tempered' sophistication of the the three-delay-line Multi mode.
    • Muted Chorus

      Here we're using the single-line Chorus mode to add some smooth and subtle movement to the signal. The Tone control is set at about 10:00 for a darker chorus sound. At :18 the speed is increased to add more motion to the sound.
    • Spinning Multi

      Clip starts in true bypass, then engages with the speed at maximum in the Multi mode. At high speeds you can generate some very fast and pleasing spinning modulations. Speed is dialed back at :29 for a less frenetic sound.
    • Steady Vibrato

      Hypnotic pitch variations, slow undulations, sea-sick warbles, and frantic insanity are all possible with the vibrato mode. This clip goes for some slow and steady moderate motion.
    • Distorto-Chorus

      Ola is great with distorted signals. This clip starts in true bypass, then goes into Multi mode. The distorted signal is fattened up, with all the organic warmth you could ask for.
    • Luscious Swirl

      Clip starts in true bypass, then engages with the three-phase Multi mode. Deep, organic, and luscious chorus tones are easy to create.

  • Audio Samples

    • Envelope Mode

      In multi mode, the 'env' setting reacts to your playing by mixing in more effect as you play louder. This opens up dynamically expressive creative possibilities, allowing you to 'dig in' and open up the sound, or lay back and dry out. The response is created with maximum transparency and musicality.
    • Envelope Vibrato

      In vibrato mode, the Env setting reacts to you playing by increasing the speed as you play louder. In this clip we've set the MIX control at about 10:00 to create a rotating speaker kind of a vibe.
    • Ramp

      The ramp mode smoothly goes from dry sound to wet at a rate determined by the RAMP SPEED knob. The effect "ramps" in as the Ramp footswitch is engaged and the chords open up as the chorus effect comes in.
    • Ramped Vibrato

      The vibrato is introduced smoothly and naturally in ramp mode, coming in at a rate determined by the RAMP speed control and engaged with the Ramp footswitch. This feature was present on a classic blue vibrato stomp box that continues to build its cult following today.

Tone Shaping

  • Types
  • Modes
  • types2

    The Chorus type is a traditional single-delay-line chorus using our dBucket algorithm. It uses a logarithmic LFO type to create a deep chorus that makes a great transition from lush to pulsing as the speed is increased.

    The Multi type has three individual dBucket delay sections per channel to create a ‘studio’ chorus effect that handles a high wet mix without sounding warbly.

    The Vibrato type employs a sinusoidal-type LFO and a single dBucket delay line per channel to capture the essence of the original classic vibrato stomps.

  • modes2

    The Envelope mode causes the effect to react to your playing level. When Chorus is selected, the wet signal diminshes as you play louder and comes back in at lower playing levels. With the Multi type, the opposite effect happens. The wet signal increases as you play louder, and diminishes at lower playing levels. With Vibrato selected, the speed of the vibrato increases as you play louder, and slows down at lower playing levels.

    In Ramp mode, press and hold the bypass footswitch to ramp in the effect. Use the Ramp knob to adjust the speed of the ramping effect. The effect ramps more quickly as you turn the knob clockwise.
