a/b + boost

[drk]

hello all!
some time ago i tryed the beginner project from here, and it worked really well so i think of putting it somewhere
went search the places where i keep "stuff" and found a a/b pedal, probably the 1st pedal i ever made!!
so i had the idea, do a a/b pedal with the booster and here it is


(sorry for the bad pictures)

the boost part has some minor changes, i took the pot, and i added a fet in the beginning, the rest is the same

one idea that i had too was to be able to change the in/out of the booster, so i could use the a/b with boost in any way(ex: 1 guitar connected to 2 amps, or 2 guitars/1amp), but i couldnt figured out how to wire the switch anyone knows a way??
thanks!!
