Hey, I claim no officiality to my posts, except when issuing new Club membership numbers. Otherwise, I'm just a normal guy, trying to make my way, like everybody else. I feel we all have something to contribute! By all means, go for it.

Cool beans, LoveJack! By flat angled I guess you mean a 90 degree plug, for the Left (mono) FX Send of the S40? But, why the TRS (stereo), when a TS is sufficient? Also, there should be plenty of room for two straight ¼" plugs. Don't mean to rain on your parade. It'll probably still work, but just hope you didn't pay extra for it. Please let us know how it works for you!
