Purchased new and only used a few times. It's in like-new condition. --Product Description-- Meridian covers short delay effects such as chorus, phaser, pitch shift vibrato, flanger, and comb filter, realizing a variety of delay time effects. Meridian is a versatile modulation pedal with beautiful tones and a practical control scheme. We have focused on ease of use while achieving both deep tones and practical operability. The sparkle of delicate harmonics synchronizes with the performance, enveloping you in a warm, analog-like tone. ・VOLUME - Controls the overall output volume. Up to 6dB boost is possible. ・REGEN - Adjusts negative feedback, enabling sound making beyond the framework of flanger and phaser. Resonant flanger and phase tones, and metallic, mechanical comb filter sounds can be obtained. ・MIX - Adjustable from 100% dry to 100% wet. Counterclockwise for more dry, Turning clockwise gives you the effected wet signal. When set to fully wet, it creates an exciting and hallucinatory vibrato. ・RATE - Allows for a wide range of speed control. Supports from an ultra-low speed of 0.12Hz (8s) to an ultra-high speed of 15.5Hz (65ms). ・WIDTH - Adjusts the intensity of the LFO modulation. At the minimum value, LFO modulation is disabled and enters comb filter mode. ・TIME - Sets the delay time range centered on modulation. Shortest 800us (0.8ms), longest 50ms ・WAVESHAPE - 3 LFO waveforms are available (sine wave, triangle wave, Flux wave) If the LFO is bypassed and WIDTH is set to minimum, the RATE control manually adjusts the delay. ・EXP jack - Adjusts RATE or WIDTH from zero to the position of each knob.
