The DigiTech HammerOn is a polyphonic pitch-shifting pedal that merges classic hammer-on effects with modern sequencing and harmonizing capabilities. Two footswitches allow for momentary pitch shifts, harmonic intervals, or complex sequences, while the second footswitch offers multiple operating modes, including Hammer On, Impossible Mode, and Sequence. Additional features such as TRILL and DRY+ provide further tonal variations, making the HammerOn capable of replacing several specialized pitch pedals. Its versatility makes it ideal for expressive lead playing, experimental riffs, and creative sound design.
