Electro-Harmonix introduces the Slammi Plus Polyphonic Pitch Shifter / Harmony Pedal featuring glitch-free pitch shifting over a +/- three octave range and with the ability to transpose up, down, or both simultaneously. An 11-position Shift switch selects the transposition interval starting with



Detune for a chorus or doubling effect and includes the following: Minor 2nd, Major 2nd, Minor 3rd, Major 3rd, Perfect 4th, Perfect 5th, Major 6th, 1 Octave, 2 Octaves and 3 Octaves.

The pedal’s Dual Mode outputs two separate pitch-shifted intervals simultaneously and provides 11 unique interval combinations. The Slammi Plus also features an X-Fade function where the pitch shifted interval is fixed (does not bend) and the pedal cross-fades between the player’s dry note and pitch shifted note or cross-fades from one pitch shifted interval to another.

The Slammi Plus is fully polyphonic at all times and provides enhanced flexibility in setting the heel position’s pitch shifted interval. A Blend control is also included that allows the user fine tune their wet/dry mix.

The Slammi Plus comes with a 9 Volt battery and also accepts most 3rd party power supplies including the optional EHX9.6DC-200mA PSU.

Electro-Harmonix has announced the introduction of a new, smooth operating Volume Pedal featuring two impedance options for maximum compatibility and housed in a rugged, lightweight chassis. With selectable 25K or 250K impedances, the Volume Pedal is well suited for both active and passive pickup equipped guitars and basses as well as keyboards, other electronic instruments and line level signals.

The EHX Volume Pedal enables the player to attenuate their signal anywhere in the signal chain and its passive design means no power is required. It is the latest offering in EHX’s Performance Series that includes the Wailer Wah, Cock Fight Plus Wah and Talking Pedal with Fuzz, Expression Pedal and Dual Expression Pedal.
