SH3 (SpaceHarp) Phaser
From the vendor
Enter a new phase with the Space Harp 3 (Small Stone V3 )!
What sets it apart from the V1 & 2? The original Small Stone designs used a transistor-based input stage, OTA based oscillator and CA3094 (EH1048) chips for the phase stages with passive output mixing.
This version (The V3) was a completely new design produced using the new (at the time) LM13600 OTA for the phase stages and an op amp oscillator, input & output stage.
