logic gates and spst
i want to create effectors for my guitar.
i built a distortion circuit.
now i need a dpdt switch.
i cant get a pedal dpdt switch for several reasons, so i thought of something else.
a simple digital system that can use an spst bottun to a dpdt switch.
it has 4 modes
1. spdt closed. effect off.
2. spdt open. effect on
3. spdt closed. effect on.
4. spst open. effect off.
in other words, the spst is turns circuit on , and when pressed second time turns circuit off.
unfortunatly, my knowledge in logic gates, and electronics generally, is limited, so i couldn't find a circuit that can do this.
ive been schetching for a while now.

glad to help,
but again a hint. You may wish to hold the gates low or high with some resisters untill you close the switch.
