Marco	Re: Need A Complete Power Supply. Hum FREE R.G., your "Spyder" is really intresting, but I hope to keep the circuit very simple: is it possible to use a single filtered power source and one "ground lifter" for each 9-volt jack? This is my idea: pedal input jack doubles as power switch: the negative of the battery (or power adapter) is in contact with the ground of the circuit (when "on", of course). Several pedals in series share a sort of "ground plane" (via audio cables and pedal boxes). If I suffer ground loops problems I can try to "lift" one or more "negative" from 9-volt cables. Is this correct? Many thanks for yor support. m.
