Quick settings
1. Start out by making the following settings.
VOLUME knob: center TONE: center
POWER SAG knob: MIN (counterclockwise) SUSTAIN: MIN
MIX knob: TUBE THRESHOLD: MIN
GAIN knob: in the 9 o’clock position
Adjust the VOLUME knob so that the level of the effected sound is
about the same as the bypassed sound (when the effect is off).
2. While playing the guitar, turn the POWER SAG knob to increase the
sag until the Nutube goes dark at the moment that you play.
If the Nutube stays lit even at the maximum setting, turn the
THRESHOLD to adjust the level.
3. Check how the compression sounds when the sag is increased.
For single-coil: the effect increases as you turn the THRESHOLD
clockwise.
For humbucking coils: turn the THRESHOLD counterclockwise to
adjust.
4. If the compression is too strong, adjust by turning the knob to the
DIRECT side to mix the direct sound.
When you mix in the direct sound with a large amount of SUSTAIN,
you can get a sound with an attack but also a long sustain.
5. Use TONE to adjust the attack feel.
We recommend that you set this to a position slightly left of center
(around the 11 o’clock position).
