EM-406 Tomahawk is a complex four-stage phaser shifter.

The module has controls for Sweep Rate, Phasing Amplitude, Notch Shift, Frequency Modulation, and Peak Emphasis.

The internal oscillator generates a unique type of Sine/ Hyper Triangular Waveform, which may be morphed using the Waveshaper control knob.

The oscillator’s wave shape itself may also be externally modulated via the dedicated CV input.

The Sweep Rate control sets the LFO's frequency—ranging from 0.2 Hz to 30 Hz.

TOMAHAWK’s phasing character ranges from gradual and thick phasing swells to rapid pulsating shifts.

The LFO's frequency rate and polarity are displayed via LED indicators.

The Phasing Amplitude modifies the LFO's impact on the phase shift, thereby functioning as a phase depth attenuator.

Exponential Notch Shift modifies the frequency position of the phase notches. The phaser's frequency may also be externally modulated using the CV In: Freq. input, and attenuated with the corresponding Frequency Modulation control knob.

Peak Emphasis modifies the phaser's resonance level. Setting this knob to its maximum level will cause the phaser to self-oscillate.

An external sweep oscillator may also be applied via the Ext. LFO In.
