Pigtronix PHI Echolution Delay/Modulation Guitar Effects Pedal

The Echolution is a dual delay, with independent Tap Tempo and Modulation delay modes. This arrangement allows the musician to switch between different delay sounds on the fly.When set to Tap Tempo mode, the Echolution has a maximum delay time of 20 seconds and a minimum delay time of 10ms. An on-board momentary switch lets the musician easily set the tempo of the delay. The Modulation Delay mode operates over three distinct time ranges, providing easy access to a huge array of delay based effects.The short setting (10ms-120ms) provides stereo chorus, reverb and slapback sounds. The medium setting (100ms-1.2sec) covers classic BBD and tape echo territory with lush modulation and rich analog sound. The long setting (1sec-12sec) allows for sound on sound, looping and reverse playback as well as rhythmic multi-tap patterns and pitch bending madness.What truly sets Echolution apart are the Multi-Tap toggle switches which introduce any combination of five additional echoes at musical fractions of the master delay time. Normally, the values of these fractions are based on quarter notes and triplets but using the PHI switch realigns all of these fractions to values based on the Golden Ratio. The Golden Ratio is a naturally occurring spiral rhythm that is found throughout the universe. It is observed in the shapes of galaxies, sea shells, DNA, the Egyptian Pyramids as well as in the work of many great musicians.Chorus (pitch) and Tremolo (amplitude) modulation of the delay signal are controlled by a single analog LFO. Independent depth controls allow both types of modulation to be blended for rotary speaker sounds and other warped effects. An Expression pedal input for changing the delay time gives the musician even further physical control over the Echolution
