Electro-Harmonix Releases the Pico Swello Attack Envelope

Housed in EHX’s Pico-sized chassis, the Swello has a simple four knob/one button layout. VOL adjusts the overall output of the pedal while ATTACK sets the attack envelope time. Low ATTACK settings attenuate just the initial attack of your instrument, while higher settings offer epic, long note swells. The Low Pass Filter is controlled by the FILTER button as well as the FREQ and MOD knobs. FILTER engages the LPF and applies an adjustable high or low resonance setting. The FREQ knob sets the cutoff frequency of the LPF and the MOD knob controls the depth and direction of the filter modulation akin to an envelope filter. Turn MOD up from noon for an upward filter sweep or down from noon for a downward filter sweep.

The EHX Pico Swello comes equipped with a standard EHX 9 Volt power supply. It will be available Mid-September and features a U.S. Street Price of $149.50.
