Strymon Ola Chorus and Vibrato Pedal

Certified Organic.

When Strymon set out to design Ola dBucket Chorus and Vibrato, they knew that they 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. Their hand-crafted, processor-intense dBucket algorithm delivers all of the warmth and sonic complexities of analog choruses and vibratos. They drew influence from some of their favorite vintage chorus effects and a certain little blue box vibrato with a strong cult following. 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.
