Chemist V2 Modulation


The Chemist v2 is a one-stop modulation laboratory featuring an analog emulating chorus, a mind altering phaser or a polyphonic organ style octave. The journey begins with two rows of identical controls, allowing you to switch between the top and bottom row with the push of a button. Always visible and editable on the fly, this works as a preset without any programming or menu diving. You can set each row to be a completely different sound. For example, set a lush chorus on one, a phaser on the other or create any combination of two distinct sounds and alternate between them instantly. For each set of controls, there is a slide switch on the side of the pedal that lets you select either “Cobalt”, a classic lush chorus, “Lithium”, a polyphonic organ octave effect or “Iridium”, a swirling phaser. Bend the sonic elements to your will with The Chemist V2.





Reaction – Controls the mix of the effect

Catalyst – Controls the speed of the phaser and chorus and the mix of the upper octave

Formula – Controls the delay time of the chorus, the resonance of the phaser and the lower octave mix


Alt Switch (secondary foot switch) – What sets the Chemist V2 apart from other pedals is the Alt controls. The three knobs on the “Top” row of the pedal are duplicated on the “Bottom” row giving you two different settings/sounds which you can jump between. You can independently select the algorithms for each row using the slide switches on the side of the pedal. This creates a simple and straightforward way to get two dynamic sounds on the fly.

Alternate Jack Out – This input allows you to control the Alt and bypass switch remotely using a TRS cable. Tip controls the Alternate Switch and ring controls the Bypass Switch.

Analog Dry Path Signal – Your instrument's dry signal path is kept completely analog while mixing in the digital wet signal creating a unique and unparalleled modulation sound.

Expression Jack – Plug in an expression pedal to dynamically control the “Formula” knob on the 2nd row of controls. This bypasses the physical knob on the 2nd row when the expression pedal is plugged in.

TRS cable required.
