The Standard Issue Phaser is based on the classic Phase 90. It's been modified to have a bit more slosh with less of that nasally, upper midrange that you would usually associate with a phaser effect. It also has two sets of depth and rate controls, so it's like having two pedals in one! The Standard Issue Phaser has been optimized to work perfectly with guitar or bass. Note: it does not protect against Klingons.
