Check the listing for details. Carl Martin EchoTone Delay Guitar Effects Pedal. Condition: New. Listed at 476.00 USD. The Carl Martin Echotone delay guitar effects pedal may just be the only delay pedal you ever need. 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), and set echo for that massive lead or solo. Combine this echo flavoring by installing a chorus, flange or even distortion pedal in the insert loop, and the switchable trail function at bypass and you get an echo effect pedal of unbelievable sound and dimension. The Carl Martin delay pedal's Echo switch activates or bypasses the Echotone, indicated by the LED on the unit being activated. Please note the Echotone is not true bypass, it features a high-quality buffered bypass, to ensure long cabling without loss.
