Manufactured in the ’90s, the Boss PN-2 Tremolo/Pan lived a short life(March-December 1990) and was replaced by the TR-2 in ’96. However, the TR-2 lacks the stereo outputs and panning effects the PN-2 has, making the PN-2 highly desirable for fans of this sound and circuitry. The PN-2 sports Rate and Depth controls and a 4-way Mode switch with Pan-sawtooth, Pan-square, Trem-sawtooth, and Trem-square wave options for super versatility.
