I am currently powering my Boss RC-300 (which requires 9V 320mA) on the last outlet of my TC-10 (on the 9V side). Is it conceivable that I could use the 12V side on that same outlet to power a pedal that can take 12V and only requires 4 mA? This way, the power draw of the two pedals would still be under 400mA, which is what that outlet can supply...sorry if that's a bit difficult to follow. I just really want to avoid having to add a walwart just for a pedal that only draws 4mA. I know this would mean the two pedals would not be isolated, but I'm wondering if anyone has done this successfully.
