Effect types

Uni-Vibe

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

More settings:

"You need it before the amp if you want the bump." source

Tip: connect a pedal or switch to the Rate parameter to control speed.

More information:

Barber Pole Phaser

Like the "Shepard" tone, this type gives the illusion of a never-ending cycle. Works best when placed at the end of the chain.

Mono or stereo

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 (mono) Cab.

Order

Increase the Order parameter to simulate phasers such as the EHX Small stone and Mu-tron Bi-Phase.

Feedback Tap

"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.

Troubleshooting

Thump when engaging the Phaser

If engaging/bypassing the Phaser block causes an audible thump or gap, change input impedance to 1M (Axe-Fx II, III and FX8).
