The Uni-Vibe effect is available as a special mode of the Phaser block. Engage the Vibe mode (or select the Classic Vibe type).
The default settings are modeled after the Fulltone Deja-Vibe. source
Put the effect before the Amp block.
"You need it before the amp if you want the bump." source
Connect a pedal or switch to the Rate parameter to control speed.
Barber Pole Phaser
Like the "Shepard" tone, this creates the illusion of a never-ending upwards cycle. Works best when placed at the end of the chain.
Set the Phaser to 6 stages to emulate a Mutron Bi-Phase.
"For the double-phaser of the original, set it to 12-stage with LFO Phase at 0." source
Set Depth to 0, attach Frequency Start to the Sequencer. Set Min and Max and adjust the Sequencer faders.
Mono and stereo output
Phaser defaults to mono to prevent phase problems when used before an Amp block. To make it stereo, change the LFO Phase setting and place it after Drive, Amp and Cab.
|Parameter||Axe-Fx III||Axe-Fx II||AX8, FX8|
|LFO Reset on Bypass||yes|
|Barberpole — Sweep Direction||yes|
|Barberpole — Filter Q||yes|
"Phasers cause notches in the spectrum which can reduce the apparent volume. It depends on the frequency content. Overdriven sounds have more content and will be affected more. The Level knob allows you to compensate for this."
Increase the Order parameter to simulate phasers such as the EHX Small stone and Mu-tron Bi-Phase.
"There is no feedback on a Script 90." source
LFO Bypass Reset
If LFO Bypass Reset is set to anything other than Off, the LFO will be reset to the selected phase whenever the block is bypassed. This allows synchronizing the sweep to the engagement of the effect.
"Another fun phaser trick is to set DEPTH to 0 and assign the Frequency Start to an expression pedal." source
Thump when engaging the Phaser
If engaging/bypassing the Phaser block causes an audible thump, change input impedance to 1M (Axe-Fx II, III and FX8).
