TUTORIAL on how to add a ground plane to a pcb in the Cadsoft Eagle layout editor.    Revised 12 May 2007

TRUE BYPASS - A diagram of the wiring of a dpdt switch for true bypass of the effect, takes it completely out of the circuit so that the sound remains true when the effect is not in use. Also, if you want to have true bypass and an LED indicator both with only a dpdt switch, check out the true bypass with LED drawing that has methods for negative ground (most effects) and positive ground (as used on PNP fuzzfaces and Rangemasters).
