About the three operating modes
Preset mode (recalling preset programs)
In Preset mode you can use the AMP switch/selector to recall programs for
each amp model: “basic” programs containing typical sounds for that amp
model, “effect” preset programs, and “song” preset programs that replicate
tones from hit songs. Each program will automatically switch the settings for
GAIN, VOLUME, TREBLE, MIDDLE, BASS, and effects. For details on the hit
songs that are programmed for each amp model, please refer to the table at end
of this owner’s manual.
Switching to Preset mode
If the PRESET LED is dark, you’re not in Preset mode. Press the PRESET
switch; the PRESET LED will light up, and you’ll be in Preset mode.
Recalling a preset program
Each of the forty-four amp models contains three preset programs: “basic,”
“effect,” and “song” (a total of one hundred and thirty-two programs).
With the PRESET LED lit, use the AMP switch/selector. The preset program
specified for each amp model will be selected, regardless of the position of the
top panel control knobs or EFFECTS selector. If you recall a preset program
while the effects bypass is enabled, the bypass will be cancelled.
In preset mode, pressing the PRESET switch will make the PRESET LED cycle
through green, orange, and red, switching among preset programs Basic,
Effect, and Song.
Manual mode
When the VTX150 Neodymium is in Manual mode, it will behave like a conven-
tional guitar amp. In other words, the sound will reflect the actual position of all
the top panel selectors and control knobs (except for the VALUE and DEPTH
knobs).
Switching to Manual mode
If the MANUAL LED isn’t lit, the unit is not in Manual mode. Press and hold
down the PRESET switch for one second or longer; the MANUAL LED will
light up, and the unit will enter Manual mode.
NOTE: In Manual mode, if you adjust a parameter setting that is not affected
by a knob position (such as the effect parameter and the noise reduction
settings), the adjusted setting will be saved automatically, and that same
setting will be recalled the next time the unit enters Manual mode. However, if
at that time the PEDAL or MOD/DELAY selector is set to a different position
than previously, the default parameter settings for that effect type will be
loaded.
