Keeley Magnetic Echo Delay Pedal Keeley Magnetic Echo – The Mag-Echo pedal simulates tube tape echo sounds by using the delay circuit and a little bit of modulation. Tape echos have long been regarded as a warm and very guitar friendly form of delay. The Mag-Echo achieves similar results by using a touch of Lo-Fi delay, a slightly filtered echo response to keep things warm, and some modulation. Modulation, or “Wow and Flutter” in the tape world is a slight pitch shift or wavering that occurs as the tape is pulled across the heads. The modulation we use is similar to what we use in our Seafoam Chorus, a slight wavering of pitch on the trails of the repeats. With a simple set of controls for the delay – Time, Regen, and Level and with the “Wow and Flutter” controls – Depth and Rate you can create some very vintage or rather unique tones. ECHO CONTROLS • Delay Time – This Time control roughly sets the length between your repeats between 40ms and 600ms. This range is well suited for classic, vintage delay sounds that are great for slap-back or medium length delay times. • Regen – 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!) • Delay Level – The Level control is your mix, how loud you want to hear the echoes. WOW AND FLUTTER CONTROLS • Depth – Turn this cont
