2 GUITAR/INSTRUMENT CHANNEL
GUITAR/INSTRUMENT jack
Connect an acoustic guitar or other acoustic instrument here.
[AIR FEEL] knob
This gives you a reverberation and ambience that’s like recording
the sound of an acoustic instrument through a mic.
You can use the knob to select between ve dierent types of mic
recording (miking).
Type Explanation
DRY
This is the traditional amp system used to directly play back
the sound from the pickups, which emphasizes the character
of the pickup sound.
Used for fully conveying the expressiveness of your
performance.
XY
Oers the advantages of the XY miking technique.
This picks up the body resonance of acoustic instruments
and the direct sound of their strings playing, which gives
percussive playing eects like muting the chord strokes or
the bridge with the palm of your hand.
AB
Oers the advantages of the AB miking technique.
This naturally extends the reverberations of the guitar into
the sound space, and gives acoustic instruments a wider
range of resonance.
ORTF
Oers the advantages of the ORTF miking technique.
Ambience is added to the reverberations of acoustic
instruments, giving them a deeper, atmospheric sound.
MID SIDE
Oers the advantages of the mid-side miking technique.
This oers an ambience that sounds like being at a slight
distance from the acoustic instrument, and is suitable for
emphasizing vocals and other musical instruments when
playing accompaniment.
