The Electro Harmonix Switchblade Plus Line Selector offers a convenient solution to players that need to quickly switch channels; whether between multiple amps multiple pedalboards or even the different channels on a single amp the Switchblade+ has you covered. The left footswitch toggles between the two locations while the right footswitch engages both simultaneously. To further enhance its functionality the Switchblade+ provides a dedicated output that can be used for a tuner or other effects pedals. This Tuner output jack is hardwired to the input jack and provides a direct output regardless of how the pedals being used. With a fully passive audio path and active LED indication the new Switchblade+ is your utilitarian sidekick.
