[QUOTE="Chris Nixon, post: 11977, member: 1947"] I have a simple normally-open footswitch that I use to input tempo information to my outboard delay unit. The problem is that it will sometimes register a delay of about 20ms when I'm trying to tap in a long repeating delay, presumably due to bouncing of the switch contacts. Setting a minimum tap value of maybe 50ms on the delay unit would probably fix it, but I don't know of anything that's an option on. It works fine if I push it with my hand, but it's normally on the floor where I hit it quite sharply with my foot. There is 3 X 3 X 2 cm of free space inside it for any components I'd want to add. I believe this would involve a capacitor, but I don't know much more than that :) I can solder, and I have some 220uf caps sitting around. Thanks, Chris [/QUOTE]
