From the vendor
The Super Phaser hails from the classic 4 stage JFet phasers that have united the world in Rock in Roll for decades, but adds a little bit of user friendliness to the classic design. We’ve added a ‘width’ control, which acts much like a depth control does to help bring some additional tweakability aside from the simple speed knob. In addition to providing this awesome project, we have a limited supply of matched 2N5952 transistors (the originals) that are available for purchase with your copy of the PCB. Simply choose which package you’d like, and swirl yourself into 80’s awesomeness!
