The BigShot EFX is a true-bypass effects loop switcher that lets you set up two separate effects loops and insert them into your pedal chain at will. This means that noisy pedals or tone robbing non true-bypass pedals that you "love to hate" can now be used and completely taken out of the signal path when they are not needed.Better yet, while an effects loop is on "standby", you can turn on and off pedals at will and prepare your sound.
