The Blackstone Phaser is a phaser pedal by Demiurge Instruments. When Delicious Audio covered it in February 2022, the site noted there was very little information available about the pedal, so what follows is what was published at the time.1
What it does
The Blackstone is a dual phaser design. Delicious Audio's Paolo De Gregorio wrote that it is "apparently, it's an evolution of an obscure Blackout Effectors dual phaser that adds an extra rate setting," and described it as "this intense phaser pedal."1
Controls
The pedal's controls center on two Rate knobs, and each one carries its own toggle1:
- Rate knobs (two): the two speeds can be switched through the Rate knob1
- Range toggle (one per Rate knob): selects a range of speed, from slow to fast1
"Each Rate knob has its own \"Range\" toggle that selects a range of speed, from slow to fast."
