The Nobels AB-1 Active Selector is a pedal for the guitarists that are experienced in using effects pedals. The AB-1 allows you to switch two input signals into one output signal or to switch one input signal into two output signals. This is a technique that is used a lot by psychedelic rock guitarists and it can lead to enormously creative sounds.
