The North Star Wobbler. Polaris is a chorus/vibrato pedal with two independent depth levels, accessible on the fly. One has resided in the shoppe since it’s inception. With it’s smooth modulation and simple controls, it was a great starting point. After recreating the circuit in a breadboard, we moved forward from there. We started by replacing the depth switch in favor of a knob on Polaris. This allows for better control of the modulation depth. Following in the steps of our Daedalus reverb, we incorporated a second depth knob that is selectable via the secondary footswitch. The original circuit did not have any tone control options. We also decided to implement a Tone knob on Polaris. This knob allows the user to add or cut lower bass presence to the signal. Once we had a tone section sculpted to our liking, we placed a master Volume knob at the end of the circuit. The Volume knob goes from full cut to slightly boosted above unity volume. These two knobs work in conjunction with each other. Lastly, we added a Mode toggle switch to seamlessly alter between chorus and vibrato modes on Polaris. The end result is a luscious, all analog chorus and vibrato pedal with tons of cool options and features.
VOLUME – Controls overall output volume. Ranges from full cut to a strong boost.
TONE – Fine tunes the low end response.Interactive with the Volume knob.
RATE – Controls the modulation speed.
FOCUS – Controls the overall modulation depth.
FOCUS II – Controls the overall modulation depth when the right footswitch is engaged.
MODE SWITCH – Toggle between Vibrato (pitch modulation: left) and Chorus (pitch duplication: right). in a sense, your natural – albeit modulated tone to the left, and a lush full sound to the right, much like our lunar graphic.
9V – Standard 5.5mm x 2.1mm center negative power supply. Polaris has internal polarity protection.
