Magnetic Echo Delay Pedal


The Keeley “Magnetic Echo” aka “Mag-Echo” Tape Echo/Delay pedal in limited “Space Echo” color scheme 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 Keeley uses is similar to what they use in the 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 – users can create some very vintage or rather unique tones.

The Echo Controls available are Delay Time, Regen, and Delay Level. Delay Time control roughly sets the length between users’ 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. The Regen control sets the number of repeats. Users 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 control is the mix, how loud the echoes are.

Wow and Flutter Controls available are Depth and Rate. Turn the Depth Control to achieve deeper and deeper chorusing and pitch shifting on echoes. As users raise the control the Depth and Rate LED will start to glow giving users a visual indication as to the amount of modulation they are applying to the repeats. The Rate Control is the Flutter control. It’s another way to control how poorly the tape echo is performing! Not that any tape deck was ever in this bad of condition, but it sure sounds good to have a little pitch modulation on the echo! Using these controls gives users a nice way to create unique and very musical delays.

Whether you’re into Rockabilly slap-back echoes, experimental sounds, or just want a great classic rock sounding echo, the Magnetic Echo will sound great in your rig!!
