The Carl Martin Echotone effects pedal features 1,200 milliseconds of vintage echo, foot-switchable Tap or Manual time settings, an insert loop and switchable trail function at bypass. Imagine switching from a Manual time setting to a Tap time setting right at your feet, so you can play with your favorite slap-back echo on rhythm to a Tap (tempo) set echo for that massive lead or solo. Combine this with flavoring your echo by installing a chorus, flange or even distortion pedal in the insert loop, and the switchable trail function at bypass, and you have what Carl Martin's test players have called ��the best echo they have ever heard.�� As with all the Danish-built Carl Martin effects, the Echotone comes in Carl Martin's low-profile housing, coated in a stunning off-white color, with the built-in 12v (+-) regulated power supply.
