The Switchblade Plus Channel Selector from Electro-Harmonix offers a convenient solution to a player's switching needs. You can route your signal to either Output A or to Output B, or send it to both outputs at once. You can also connect a tuner or effects pedal to the Tuner output which is hardwired to the Input jack and provides a direct output regardless of the state of the unit. This pedal features a fully passive audio path and active LED indication.
The Switchblade Plus has two footswitches for A/B Mode and A+B Output select, as well as two LEDs acting as Mode and Output indicators. In A/B Mode the left LED is red when routing to Output A and green when routing to Output B; the right LED lights red when the input signal is going through both Outputs A and B.
The Switchblade Plus can be powered by a 9V battery or 9 VDC power supply, and can also operate without any power source, since the audio path is fully passive. However, when using without a power source the LED indicators will not function.
