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 its 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.
