LIMITER
The limiter attenuates loud input levels to prevent distortion.
Parameter Value Explanation
TYPE
Selects the limiter type.
BOSS LIMITER This selects a stereo limiter.
RACK 160D This models a dbx 160X.
VTG RACK U This models a UREI 1178.
THRESH 0–100
Adjust this as appropriate for the input
signal from your guitar. When the input
signal level exceeds this threshold level,
limiting will be applied.
RATIO 1:1–INF:1
This selects the compression ratio used with
signals in excess of the threshold level.
LEVEL 0–100 Adjusts the volume.
ATTACK 0–100
Adjusts the strength of the picking attack
when the strings are played. Higher values
result in s sharper attack, creating a more
clearly dened sound.
RELEASE 0–100 Adjusts the release time.
SUB OD/DS
This eect distorts the sound to create long sustain.
Parameter Value Explanation
TYPE

DRIVE 0–120 Adjusts the depth of distortion.
TONE -50–+50 Adjusts the tone.
EFFECT LEVEL 0–100 Adjusts the volume of the OD/DS sound.
BOTTOM -50–+50
Adjusts the tone for the low frequency range.
Turning this to the left (counterclockwise)
produces a sound with the low end cut;
turning it to the right boosts the low end in
the sound.

cut lter begins to take eect. When FLAT is
selected, the low cut lter will have no eect.
HIGH CUT
630 Hz–12.5 kHz,
FLAT
This sets the frequency at which the high
cut lter begins to take eect. When FLAT
