I also go from one type of delay to another and would need to hold it for 2 second to turn off, change patch, hold for 2 seconds, turn on, then start tapping again. The £4 it cost me off eBay seemed worth it for practicalities sake...[/quote]
Fair enoguh, it's never really bothered me with mine, but I don't change patches that much, I either set it to a nice general delay or knob-twiddle of oscillaty noise craziness.
