This should be compared to the vintage model EHX Bad Stone™ Phaser. The project includes true bypass switching, the auto/manual switch and of course the phase/vibrato switch of the old unit. We have added a clean boost on the output along with 2 individual internal trimmers so the volume of each mode (Phaser/Vibrato) can be tailored to preference.
Each Bloodstone PCB now comes with a complimentary CD4009 chip, while supplies last. CD4009 is out of stock at this time.
Change to V.1.1: Orientation of Q2 corrected.
