The Voodoo Lab Amp Selector is the ultimate stand-alone tool for switching your guitar into multiple amplifiers. It lets you use up to four amps simultaneously without added hum or loss of tone. You can switch between or layer amps in any combination. The switching is absolutely silent with no clicks or pops.

The Amp Selector fulfills several indispensable real world applications for guitarists. Each of the outputs can be directly switched, allowing you to layer any combination of amps simultaneously. It can also be configured as an A/B/C/D box for selecting between up to four amplifiers with a single button press.

The Amp Selector features a buffered tuner or split output for slaving additional devices without loading down your pickups or muddying your tone. A second input can be used for a stereo signal path, or to switch two instruments into different pairs of amplifiers.
