LM386 bypass

(I wasn't sure whether this should have gone in the main Amplifiers section instead, but I think it's a newbie-ish enough question...)

I've noticed that although the Ruby uses only a 100nF, and the Little Gem and Little Gem 2 don't use any at all, some cursory Googling suggests that a 10uF or so cap from pin 7 to ground on the LM386 goes a long way to reducing noise, and I see that (for example) n9voc tends to use them in his schems.  Is there any reason not to add those in to the Fetzer-Little Gem MkII I'm building?
