of the amp?
Is the power cable plugged into an AC outlet?
Is the AC outlet switched on?
Does the AC outlet being used actually work?
Does the power cable work?
2. There's no sound coming from the amp
Is your guitar turned up?
Are both ends of your guitar cable plugged into where they should be?
Is your guitar cable working?
Is the amp's MASTER volume turned up?
Do you have headphones or anything else plugged into the amp's PHONE OUT
jack? If "yes," unplug!
Is the amp in "Silent Tuning Mode" (this is indicated by " " in the BANK Display)?
If "yes," get out of it by hitting the TUNER/CANCEL button.
Using the ORIGINAL VALUE LED, check the settings of the GAIN, VOLUME,
TREBLE, MIDDLE and BASS (on certain AMP TYPES, if the EQ controls are all
turned down, there will be little or no sound coming from the amp due to the way
the circuit of the original works). And, if a PEDAL is being used, check the DRIVE
and LEVEL settings.
Are you in MANUAL MODE (this is indicated by " " in the BANK Display)? If yes,
turn the following controls above their minimum setting: PEDAL DRIVE & PEDAL

Is your guitar turned up?
Is the amp's MASTER volume turned down low?
How is the POWER SELECT knob on the rear panel set?
Have you connected a high impedance (eg: 16 Ohms) speaker cabinet to the
EXTERNAL SPEAKER OUT(s)?
Using the ORIGINAL VALUE LED, check the settings of the GAIN, VOLUME,
TREBLE, MIDDLE and BASS controls (on certain AMP TYPES, if the EQ controls
are all turned down, there will be little or no sound coming from the amp due to the
way the circuit of the original works). And, if PEDAL is being used, check the
DRIVE and LEVEL settings.
