From the vendor

Dimension chorus is a legendary effect in the guitar world. Created by having two independent choruses driven by out of phase LFO signals, it creates a gorgeous modulation effect without the “wobbly” characteristic of a standard single chorus. It's presence in the DIY world is not well represented as it is both complex and traditionally utilizes analog BBD devices. If you want to build one yourself, you are usually limited to two options: the classic Boss DC-2 clone or the Dimension P DIY project. Both have their pros and cons. The DC-2 clone gets you the sound, but it has a very high parts count, uses expensive and hard to find chips, etc. The Dimension P is significantly easier to build and is based around the ubiquitous PT2399, but the PT2399 is not a great chorus chip, so you really only get an approximation of the sound. Not bad, necessarily, just not accurate.
