Electro-Harmonix - Slammi Plus Polyphonic Pitch Shifter Pedal with Dual Mode and Expression Sweep Control

The Electro-Harmonix Q-Tron Plus Envelope Filter offers expressive filtering with added flexibility through its built-in effects loop. This allows external effects to be inserted without affecting the envelope response, expanding tonal possibilities. Controls for gain, resonance, and sweep direction provide detailed sound shaping, while selectable filter modes offer low pass, band pass, and high pass options. The response switch adjusts how quickly the filter reacts to playing dynamics. Built for expressive and dynamic performance, the Q-Tron Plus is ideal for musicians seeking advanced filter effects in both live performance environments and studio recording applications.

The Electro-Harmonix Pitch Fork Plus delivers advanced pitch shifting with dual independent engines that allow complex harmonies and layered tones. Each engine can shift pitch up or down over a three octave range, with precise detune control for subtle variations. Dedicated volume controls for each voice and dry signal enable flexible mixing, while multiple routing options expand signal path possibilities. It includes preset storage with the ability to save and recall numerous programs for quick performance changes. Expression and external control inputs allow real time parameter adjustments. Designed for precision and versatility, the Pitch Fork Plus is ideal for musicians seeking advanced pitch effects in both live performance environments and studio recording applications.

One of Electro-Harmonix’s most popular effects, there are many reasons to love the POG2. One major reason being its unique attack filter, applying attack envelopes to each individual note played whether in single notes or in a chord. This creates a very musical, multi-voice effect that’s extremely adaptive to any musical style. This polyphonic attack filter is the core of the PICO Swello generating polyphonic and reverse sounds with the addition of a modulated low-pass filter for even more expressive tones. Implemented subtly, the Swello adjusts your guitar’s attack to sound smooth and flowing even while playing fast lines and arpeggios. Laying on the effect more heavily creates dramatic swells perfect for shaping gently shifting ambient soundscapes and synth style pads. The simple 4-knob control layout is easy to drive starting with the heart of the pedal, the ATTACK knob. Turn up ATTACK to go from a quick, gentle attack time to slow, long swells. VOL controls the overall output and is useful for making up for the perceived low volume of long attack effects. The rest of the controls apply to the Low-Pass Filter. The Filter Button engages the LPF with adjustable low and high resonance settings. The FREQ control adjusts the cutoff frequency of the LPF. The MOD knob controls the depth and direction of the LPF envelope for upward or downward filter sweeps over a narrow or wide range of frequencies limited by the cutoff frequency. The LPF’s modulation timing is tied directly to the ATTACK knob setting. Combining the LPF with the Attack Envelope brings added musicality and expressiveness to fan-favorite effect, now in its very own pedal.
