In designing the Ola dBucket Chorus & Vibrato, Strymon started with the dBucket blueprint and used it to craft a beautiful and versatile modulation effect. Keeping in line with the same philosophy as the El Capistan delay, their high-performance DSP is entirely dedicated to and focused on providing the lushest and most organic chorus and vibrato sounds available. They also drew influence from some favorite vintage modulation effects and a certain little blue box vibrato with a strong cult following. On top of that they threw in true bypass, a 'favorite' preset switch, stereo input and output, and a super high quality analog front end and output section.
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.
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 Vibratoselected, 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.
