The StoneFish is a versatile modulation pedal with all analog circuitry, featuring tone and width knobs on top of the standard rate and depth knobs. The tone knob enables you to have that sparkly 80's chorus or to tone down the high end when using after a distortion pedal. The width knob changes the delay time to have the effect mellowed, like vintage chorus or drastic like modern choruses.
There's a toggle switch that cuts out the dry signal,yielding a vibrato effect that can be then adjusted further by the knobs. The lfo has enough range for the chorus to be slow and lush but also fast enough for a pseudo Leslie tones for the Vibrato. Lastly,you can even turn off the lfo (by setting the rate and depth knobs to zero) and use the width knob as a manual chorus. This enables you to set a passive chorus spot that resonates in a very unique way. Can sound like you're playing inside of a big tube.
