The Electro-Harmonix Switchblade Channel Selector is capable of carrying out all of your simple switching needs without having to worry about batteries and power adapters. Switch your signal between two different amplifiers, two different pedal boards or two different speaker cabinets. Flexible channel switching built into a compact die-cast case.
The footswitch switches the Y jack connection between the A jack and B jack.
Using the Switchblade to switch between two instruments: plug the instruments into jack A and jack B using 1/4" instrument cables. Then connect jack Y to the next device in your signal chain (effects, if any, or amplifier if none). Use the footswitch to switch between the instruments.
Using the Switchblade to switch between two amplifiers: plug the amplifiers into jack A and jack B using 1/4" instrument cables. Then connect jack Y to the previous device in your signal chain (effects, if any, or instrument if none). Use the footswitch to switch between amplifiers.
The Switchblade is not limited to the above two applications. Here are two more application examples:
Y: Instrument --> Effects chain A, Effects chain B
Y: Amplifier head ---> Speaker cabinet A, speaker cabinet B (be sure to use speaker cable and not instrument cable for this application).
The Switchblade is a passive device and requires no power supply, such as a battery or power adapter. The Switchblade does not support stereo use and will only work with 1/4" mono cables.
