Yeah...I was half-kidding...but I don't think you'll find anything really longer than that in a simple stomp pedal.
I searched long and hard for real long analog delay. I have a nice tape delay unit, vintage Multivox, similar to the Roland Space Echo...endless tape loop, etc. I wanted a pedal that was analog but could do real long stuff....in the end, I went with a Pigtronix Echolution, which is a hybrid analog/digital.
I also have a Vox Time Machine (the one that Satriani endorsed, the green unit) that I use in the studio when I'm just jamming. It does the delay digitally, but the dry stays analog.
It's nice...I just find it's got too much level even when I have it practically off....where I want just that "shadow delay" sound, and not the distinct ping delay.
It seems all the delay boxes are like that...way over the top in the amount of delay you get even at low level settings.
Anyway the Echolution kicks ass...and it's like so much more than a "delay"....but it may be overkill for a simple delay stomp to have on your pedal board.
