BlueshiftSpatial Chorus

From the vendor

Project description

The Blueshift Chorus is a faithful clone of the BOSS DC-2 Dimension C—widely regarded as the best stompbox chorus ever made as well as being one of the most coveted Boss pedals out there. It’s never had a proper DIY project due to the sheer complexity and number of components, but those days are over. The Blueshift is the first serious DIY adaptation of the DC-2—and if that wasn’t enough, it’s designed to fit in a 125B enclosure, no larger than the original.

The DC-2 is different from other choruses in that there are actually two clock+BBD pairs, each powered by either the inverted or non-inverted output of a single LFO. These BBDs then modulate the dry signal so that signal “A” reaches its maximum delay time when signal “B” reaches its minimum and vice versa as they criss-cross back and forth. The average remains constant between the two signals and only the space between the two signals is modulated. The DC-2’s effect is often referred to as motionless because it doesn’t have the signature “warble” or unsteadiness of a traditional chorus with a single BBD.

Note: This project uses a type of capacitor that has been temporarily discontinued by WIMA. Please see our news article about the issue and the substitution spreadsheet for project-specific recommendations. We are stocking a limited supply in the mean time. The build document has not yet been updated to reflect this.
