From the vendor

The SH2 is a 4 stage DIY PHASER project based on the EHX V2 Small Stone. This is the version that comes to mind when most players think of the classic effect.

Compared to our original Spaceharp project (which was the older V1), this one uses a different input stage, feedback network/color sound, and a different LFO section.

ERRATUM: The silkscreen on the rear of the pcb reads 100KB for the rate pot. This should read 1MC, as listed in the build doc.
