Mosky Magnetic Delay Guitar Effect Pedal Time Depth Rate Regen Level As Keeley Mag Echo Time Knob? This Time control roughly sets the length between your repeats between 40 ms and 600 ms. This range is well suited for classic,vintage delay sounds that are great for slap-back or medium length delay times. Depth Knob? Turn this control to achieve deeper and deeper chorusing and pitch shifting on your echoes. As you raise the control the Depth and Rate LED will start to glow giving you a visual indication as to the amount of modulation you are applying to the repeats. Speed Knob? This is your Flutter control. It?s another way to control how poorly your tape echo is performing! Not that any tape deck was every in this bad of condition, but it sure sounds good to have a little pitch modulation on your echo! Using these controls gives you a nice way to create unique and very musical delays. Regen Knob? This control sets the number of repeats. You can set this for a single slap back echo or turn it up for a runaway, self-oscillating or self-regenerating echoes. (Now go back and twist the Time control for some crazy sounds!) Level Knob?
