FS300 Footswitch Errors with EDP

["Gary Lehmann" <relayonemanband@cts.com>]

Greetings--
I got the resistors from Digikey and wired them in, but I still get the 
same
error.  Here it is:
When controlling the Echoplex Digital Pro from the FS300 footswitch, the
multiply switch occasionally also triggers the overdub.  Sometimes it does
this instead of multiplying.  The resistor in question is a 7.87K 1/4W 1%
metal film.  Is there any hope for this setup or do I need to go back to 
the
EDP footswitch?
