Fulltone Tape echo's use a relay-activated footswitchable Echo Cancel… Unlike vintage Echoplexes, Fulltone Tape Echoes don't route the playback head signal through the echo cancel footswitch, which absolutely kills the delay sound if you use a cable over 6 feet in length. With the Fulltone ECF you can use any standard guitar cable up to 500ft if need-be. And there’s no need to power the ECF to see its bright Red & Green LED’s as the power is taken from the TTE or SSTE through the cable connected to it... Pretty slick, eh? 

For use with all SSTE's. Also for use with TTE's having serial #3480 or higher.
