Help for a newby?

[jharasym]

Howdy, I've never actually built any electronics, but have a strong DIY drive and some experience soldering. I'd like to start by making a simple on/off switch (with LED to indicate status) for a self-contained Garnet reverb unit. I haven't been able to find a schematic for this on the 'net. Perhaps it's too basic? Could anyone direct me to such a schematic? Thanx
