Now you can downtune as much or as little as you like without having to change guitars! The DigiTech Drop polyphonic drop tune pedal allows you to drop your tuning in eight selectable steps from one semitone all the way down to a full octave. A ninth setting lets you go down an octave and add the dry signal too, which produces an enormous fat sound. The Drop also features a momentary/latching switch. With the switch set to "ON", you can turn the Drop into a true performance pedal, as the effect will be enabled or disabled only as long as the footswitch is pressed and held. Setting the switch to "OFF" means the footswitch acts like a regular latching on/off switch. The Drop comes with its own DC power supply.
