Strymon Ola dBucket Chorus & Vibrato Pedal

Get Truly Organic Chorus And Vibrato – The Strymon Ola dBucket Chorus & Vibrato Pedal

When Strymon set out to design Ola dBucket Chorus and Vibrato, they knew that we wanted to take a high-performance SHARC DSP and dedicate all of its horsepower to doing one thing – providing the lushest and most organic chorus and vibrato sounds ever heard.

Chorus & Vibrato Workhorse

Their 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.

Tone Shaping:

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.

Modes

The Envelope mode causes the effect to react to your playing level. When Chorus is selected, the wet signal diminishes 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.
