Morley PPA Pik-Percussion Attack Pedal

"The new Electro-PIK-Percussion incorporates all the features of the PIK-Attack plus the ability to control decay time and character. An entire range of clean cutting, sharp percussive effects ist the result. Abrupt decay of a strong harmonic enables the musician to create and produce sounds like a banjo, mandolin, and many other musical sounds with the Percussion Shaper, Repeater and speed control.
The speed, or ragte, of decay of the signal is controlled by the position of the pedal. The Eoectro-PIK-Percussion is also ideal for solo work when dominating, cutting through sounds are desired. The PIK-Perkussion can also be used as a superb, standard Morley Volume pedal."  (Morley Catalog 1980)
