Chapter 4 The Effects Explained
Sens
This adjusts the Enhancer sensitivity. The more the value is
increased, the more softly you can play and still have the
effect applied.
Freq (Frequency)
Sets the frequency range for the enhanced sound.
Mix Level
Adjusts the amount of enhanced sound added to the mix.

■ SG: Slow Gear

This produces a volume-swell effect (similar to how a violin
is played).
Parameter Value
Sens 0–100
Rise Time 0–100
Sens
This adjusts the sensitivity of the slow gear. When the
sensitivity is set to a lower value, the effect of the slow gear
can be obtained only with somewhat stronger picking, while
no effect is obtained with weaker picking. When the
sensitivity is raised, the effect is obtained even with weak
picking.
Rise Time
This adjusts the time needed for the volume to reach its
maximum from the moment you begin picking.

■ DEF: Defretter

This effect allows you to use a conventional bass to simulate
a fretless bass.
Parameter Value
Sens 0–100
Attack 0–100
Depth 0–100
Level 0–100
Sens
This controls the sensitivity to the input sound. Adjust this
setting while playing your bass until you obtain the most
natural-sounding tone changes.
Attack
Adjusts the tone of the attack portion of the sound. The tone
changes more slowly as the value is increased.
34
Depth
This controls the ratio of harmonics. Raising the value
increases the harmonic components, resulting in a unique
and different tone.
Level
Adjusts the volume.

■ R.M: Ring Modulator

This effect combines the bass sound with the sound from the
internal oscillator, creating a sound with a pitchless, metallic,
bell-like character.
Parameter Value
Mode Normal, Intelligent
Frequency 0–100
Effect Level 0–100
Direct Level 0–100
Mode
Selects the ring modulator mode.
Normal:
This is a regular ring modulator effect.
Intelligent:
The oscillator frequency changes according to the pitch of the
input sound, yielding a sound with more distinct changes in
pitch, something that differs from the effect you get with the
"Normal" setting. This effect won't sound right unless the
pitch of the bass is detected correctly. So it's best to use this
effect only when playing notes one at a time.
Freq (Frequency)
Adjusts the frequency of the internal oscillator.
Effect Level
Adjusts the volume of the processed sound.
Direct Level
Adjusts the volume of the direct sound.
