Troubleshooting
1. Power does not turn on when you turn the
POWER switch on
• Is the power cable connected to the rear panel AC power inlet?
• Is the power cable connected to an AC outlet?
• Could the AC outlet be malfunctioning?
• Could the power cable be damaged?
2. No sound from the amp
• Could your guitar’s volume be turned down?
• Is your guitar cable connected correctly?
• Could your guitar cable be broken?
• Could the top panel MASTER volume be turned down?
• Could headphones be connected to the top panel PHONES jack? If so, discon-
nect them.
• Check the settings of the GAIN, VOLUME, TREBLE, MIDDLE, and BASS
controls. For some amp models, there may be no sound from the amp if the
TREBLE, MIDDLE, and BASS controls are turned down, just as for the cir-
cuitry of the original amp.
• If the VTX150 Neodymium is in Manual mode (MANUAL LED lit), could the
GAIN, VOLUME, TREBLE, MIDDLE, and BASS controls be set to 0 or the
minimum value?
• Could the VOLUME pedal of a VC-12SV connected to the VTX150 Neody-
mium be set to the minimum position? Alternatively, could the expression
target be set to the GAIN parameter of the amp or pedal effect, with the
expression pedal set to the minimum position?
3. Insufficient volume from the amp
• Could your guitar’s volume be turned down?
• Could the MASTER volume be turned down?
• Could the POWER LEVEL be turned down?
• Could a high impedance speaker (e.g., 16 ohms) be connected to the EXTEN-
SION SP jack?
• Check the settings of the GAIN, VOLUME, TREBLE, MIDDLE, and BASS
controls. For some amp models, there may be no sound from the amp if the
TREBLE, MIDDLE, and BASS controls are turned down, just as for the cir-
cuitry of the original amp.
• If the VTX150 Neodymium is in Manual mode (MANUAL LED lit), could the
GAIN, VOLUME, TREBLE, MIDDLE, and BASS controls be set to 0 or the
minimum value?
