9.3.6 Phaser

A phaser is an effect that uses a comb-like ﬁlter to create a series of notches

in its frequency response. These are then usually time-modulated or swept

across a range of frequencies.

The Phaser in the PedalPro is implemented using six custom-made optical

resistors and produces a sound just like the shimmering tones typical of the

70’s (and similar to the Morley Pro-Phaser*).

But the PedalPro Phaser outperforms any classic vintage equivalent. Pedal-

Pro uses six OP275 operational ampliﬁers that allow for a far greater transpar-

ency, an ultra-low noise output, and an incredible modulator ﬂexibility.

The phase and the Phaser’s modulating waveforms is completely under your

control, and can be synchronised with any other phase-controlled effect.

PARAMETERS

• To enter the Phaser conﬁguration page, press the multifunction key [10a]

labelled ‘Phasr’ on page 2 of the main menu.

Phaser – Phaser effect switch. Range: on (

), off (

)

• To add (

) or remove (

) the analogue Phaser from your effect chain,

press the BYPASS EFFECT 1 key [10a].

Manual – Manual phase shift selection. Range: 0-100%

When you set the Depth parameter (see below) to 0, the amount of phase

shift then depends on the level assigned to the Manual parameter.

• To change the amount of manual phase shift to the signal, press EDIT [5],

and use the arrow keys [3] to position the blinking cursor next to Manual.

Adjust the value with the selection dial [4].

Tempo – Speed of the modulator. Range 3 BPM (20 s) - 550 BPM (9.16 Hz)

• To change the Tempo of the modulating waveform, press EDIT [5], and

use the arrow keys [3] to position the blinking cursor next to Tempo. Ad-

just the value with the selection dial [4].

Wv – Modulating waveform. Range: sine, trig, trap, rect, pcal, shlf, vntg

The Phaser has many modulating waveforms from which you can choose. All

the classic waveforms are included, along with some exclusive VR-designed

waveforms. Available waveforms include: sine, triangle, trapeze, rectangle,

pcal (phaser calibrated curve, linear phase sweep), shlf (shelf), vntg (vin-

tage). (see Appendix A for more details on the modulating waves).

• To change or select a modulating waveform, press EDIT [5], and use the

arrow keys [3] to position the blinking cursor next to Wv. Adjust the value

with the selection dial [4].

Depth – Depth of the modulation. Range: 0-100%

The depth parameter controls the depth of the phaser effect.

• To alter the depth of the Tremolo or Panner effect, press EDIT [5], and use

the arrow keys [3] to position the blinking cursor next to Depth. Adjust the

value with the selection dial [4].

Ph – Phase of the modulator. Range: 0°, 90°, 180°, 270°

The phase of the modulator controls the phase of the modulating waveform.

It is used to control the relative phase among effects that offer the possibility

of selecting the Phase of the Modulator (Ph), e.g., Tremolo/Panner, Phaser,

Auto Filters, Chorus. (For more details refer to the QUICK TIP box ‘Phase of the

modulating waveforms’, on page 27).

• To alter the phase of the Tremolo or Panner effect, press EDIT [5], and use

the arrow keys [3] to position the blinking cursor next to Ph. Adjust the

value with the selection dial [4].
