This pedal is compact in design (the same height as an MXR pedal) and has two SUPER BRIGHT LEDs. The "Pancake" option allows both channels (A&B) to be active. The "Side to Side" option allows either channel (A or B) to be active. This is one of the sweetest pedals around for A/B/Y options. There is a slight pop due to switching configurations, but not as loud as those commercially made pedals. Keep on keepin on, and buy yourself a Tru Playa!
