Longest delay pedal to practice licks & riffs?

[gc]

Can anyone suggest the longest delay pedal/settings to practice licks - play a lick or riff and then immediately listen to it once. The idea is to be able to set the delay for a few or several seconds to play longer locks or riffs. I know looper does some of this. The longest I've found is " analog delay" 2 sec with delay repeat 0 amd silver button toggled right. I have fx22 elite which includes pedals.. I can then add the pedal to any preset and have "riff and listen" mode. Thanks & happy holidays!
