Q exerts a different effect for BLOCKING or SHELVING EQ types, selectable for bands 1 and 5.
GAIN
– Sets the strength of the filter through a range of +/- 12 dB.
TYPE
– The first and last bands have a selectable filter type. This parameter selects between the three
available types.
Shelving
– This type equally boosts or cuts all frequencies above or below the specified frequency,
forming a “shelf.” The typical bass or treble controls of most devices are shelving EQs.
Peaking
– A peak filter cuts or boosts around a center frequency. When you boost or cut, neighboring
frequencies are also affected somewhat, depending on the bandwidth, or Q, of the band. Bands 2, 3, and
4 are always set to this type.
Blocking
– The blocking filter is so named because it only allows frequencies above or below the cutoff
frequency to pass through. Band 1 is selectable as a low-blocking type and Band 5 is selectable as a high-
blocking type.

Phaser [PHA]
The Phase Shifter, or
Phaser
, works by cascading a series of all-pass filters and then mixing the processed signal
with the input. This causes certain frequencies to be canceled or reinforced, creating notches and peaks. When
phase is shifted using a low-frequency oscillator (LFO), these peaks and notches sweep up and down the frequency
range to create the phaser’s distinct, hollow, swooshing sound.
The phaser in the Axe-Fx II is extremely powerful. It allows two to 12 stages to be cascaded with positive or
negative feedback and a flexible, stereo LFO. It also offers a special mode to recreate the classic ‘vibe effects with
astonishing accuracy.
Each Axe-Fx II preset can use two fully independent
Phaser
blocks.
