OTA based phaser
Neckbrace is a three stage OTA based phaser that lives where most phasers don't. With it's simple interface, it's extremely easy to create subtle to extreme jet-star-screaming modulation to inspire your creative endeavors. Those who are looking for an alternative to the classic orange box will find a more full and lush sound. And for those of you who love that slow creeping modulation you will be smitten with Neckbrace's 17 seconds cycle time at the slowest.
