Hey, does anyone know if there is a pedal like the whammy pedal, but only for dropping your guitar tuning?

Thanks, Adam
There is the Morpheus Droptune, if that's what you mean?
Gibson Les Paul Studio
Highway One Telecaster
Dean Evo
Mesa F-50
Laney GH50L
Vox AC30 C2
Ampeg V2
Morpheus Droptune.

Another one which is going to be released is the Whammy DT by Digitech, which does all the Whammy pedal functions + the Drop Tuning, no idea how good it will sound though.

The Drop Tune is pretty much the best pedal for that out there AFAIK.
