A pitch-shifting pedal controlled by an expression pedal. Can shift pitch up or down in real time, creating dive bomb effects, harmony lines, and otherworldly sounds. A signature tool for Tom Morello and Jack White.
Plug an acoustic with a piezo or magnetic soundhole pickup into an interface and the result almost always sounds wrong — quacky, brittle, missing the body. The good news is the problem is mostly in five specific frequency regions, and you can fix it with EQ before reaching for a DI box upgrade.
