Phaser stereo or mono 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 (mono) Cab.

Phaser Feedback Tap parameter

• Cliff: "There is no feedback on a Script 90." source

Preventing thump when engaging Phaser

• If engaging/bypassing the Phaser block causes an audible thump or gap, change Input impedance to 1M.

Controlling the start of the Phaser sweep

• Use the parameter “LFO Bypass Reset”. When set to 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.

Uni-vibe effect

• The Vibe effect is a special mode of the Phaser block. Set Vibe Mode to On (or select the Classic Vibe type).
• Tip: connect a pedal or switch (via an external controller) to the Rate parameter to control speed.
• Excellent Robin Trower vibe settings.
• Cliff: "You need it before the amp if you want the bump." source

Barber Pole phaser

• This phaser type works best when placed at the end of the chain.
