Description
The SpaceHarp is a 4-stage phaser based on the early EHX Small Stone v1, utilizing 3 LM13700 OTA chips rather than out-of-production CA3094’s. Features include an internally-switchable jfet-buffered input, and trimmable lpb-1 boost on the output for crystal clean makeup volume.
Changes for V1.2: pcb error for C8 has been repaired, the color toggle now switches up & down rather than side to side.
