Chapter 4 Introduction to Effects and Parameters

ACS (Advanced Compressor)

This is an effect that produces a long sustain by evening out the volume level of the input signal. You can also use it as a “limiter” to suppress only the sound peaks and prevent distortion.

D-Comp

Sustain

0–100

Attack

0–100

Tone

-50–+50

Level

0–100

Type

Selects the compressor type.

Stereo Comp This selects a stereo compressor.

BOSS Comp This models a BOSS CS-3.

D-CompThis models a MXR DynaComp.

Sustain

Adjusts the range (time) over which low-level signals are boosted. Larger values will result in longer sustain.

Attack

Adjusts the strength of the picking attack. Larger values will result in a sharper attack, creating a more clearly defined sound.

Tone

Adjusts the tone.

Level

Adjusts the volume.

LM (Limiter)

The limiter attenuates loud input levels to prevent distortion.

Type

Selects the limiter type.

Stereo LM This selects a stereo limiter.

Rack 160D This models a dbx 160X.

Vtg Rack U This models a UREI 1178.

Attack

Adjusts the strength of the picking attack when the strings are played. Higher values result in s sharper attack, creating a more clearly defined sound.

Threshold

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

This selects the compression ratio used with signals in excess of the threshold level.

Release

This adjusts the time from when the signal level drops below the threshold until when limiting is removed.

Tone

Adjusts the tone.

Level

Adjusts the volume.
