The CopperSound Polaris chorus is an all analog chorus vibrato pedal with a master volume, tone section, rate control, and two independent depth levels accessible on the fly – inspired by the MN3007 BBD chip. We started by adding the depth switch in favor of a knob. This allows for better control of the modulation depth. Following in the steps of Daedalus, we incorporated a second depth knob that is selectable via the secondary footswitch. The original circuit did not have any tone control options. We decided to implement a Tone knob on Polaris too. 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. The end result is a luscious, all analog chorus vibrato pedal with tons of cool options and features. The North Star Wobbler.
