funky footswitch

[Kriist@aol.com]

the multiply footswitch on my edp works every now and then
i have to tap it several times and hope that it works
where as the one on the front works all the time
the footswitch is relatively new
it hasnt been banged up or anything of the sort
and all the other buttons work well
would this be a problem with the actually button or the capacitors
any one with similar problems?
