The Electro-Harmonix Slammi is a flexible polyphonic pitch shifter pedal with EHX's famous "glitch-free" shifting technology. Step right up and plunge into huge three-octave dive bombs, dial in the perfect harmony for your solo, sweep around the range for intense shift effects, keep it subtly rocked for a smooth chorus sound, and blend your dry signal back in for huge tonal possibilities. With a rugged housing and top-notch build quality, the Slammi shifter is ready for the rigors of the road.
