This model of phaser popped up in 1978 and was made in this format for a couple of short years. The three knob setup gives you heaps of scope to dial in what you're after. The feedback control sends the signal back through the effect for another round; very cool. There's a few orange vintage phasers around, this one is definitely one of the best sounding options in the genre.
