What is a chorus effect

• Wikipedia

Position of the Chorus block

• Its a matter of personal preference where you want to put the Chorus block: before or after the Amp block. When placed before the Amp block, make sure the Chorus is set to mono (default).

Mono or stereo

• Chorus is a stereo effect, but defaults to mono to prevent phase problems when placed before an AMP block. To make it stereo: set LFO Phase to 90 or 180.

Number of chorus voices

• Selecting more than 2 voices is useful only when LFO Phase is not zero. More information

Chorus types

• The Axe-Fx II Chorus block lets you choose between various predefined types.
• See the manual for tips on obtaining a Dimension D-type chorus. And read this thread.

Vintage Tape

• Firmware 7.00: "Added “Vintage Tape” type to Chorus block. This type uses the tape delay algorithm used in the Delay block as the basis for the chorus effect. Note that this type sums the left and right block inputs into mono so use caution as stereo cancellation may occur."

Where's the vibrato

• There's no dedicated vibrato effect block. You can create this using chorus.
• A classic "VB" pedal vibrato effect typically uses a TRIANGLE waveform for the LFO, but the classic "CE" vibrato uses SQUARE.
• Matt Picone: "A Vibrato effect causes pitch to vary periodically, creating a "warble." This can be created easily on the Axe-Fx using the Chorus (block) set for mono and the Mix at 100%. Vibrato depth and rate may be set as desired. You may wish to set chorus Auto Depth to "OFF" for more dramatic vibrato effects."
• Scarr: "For any "vibrato mode" conversions, turn the mix to 100%. The rumour is just the Boss VB-2 was a CE-2 without the dry signal mixed in (and pedal ramp on depth). A switch to disable the dry signal is a popular CE-2 mod." Source
