range of 438 Hz–445 Hz. You can use the [▲]/[▼] buttons to calibrate
this in the range of 438 Hz–445 Hz. When doing so, the program/value
display will indicate a value of 38–45.
When you turn off the power, the calibration adjustment you made will
be discarded and the AX3A will automatically be set to 440 Hz.

cause malfunctions (such as battery leakage). You should also
remove the batteries if you won't be using the AX3A for an ex-
tended time.
❑ Have you have inserted a stereo cable into the INPUT jack?
When operating the AX3A on batteries, the power will not turn
on if you insert a stereo cable. Be sure to use a mono cable.
❑ Is the AC adapter connected to the rear panel DC9V jack?
❑ Is the AC adapter plugged into an AC outlet?
❑ Could the AC adapter be damaged?
2. No sound
❑ Is the volume of your guitar turned down?
❑ Is your guitar cable connected correctly?
❑ Is your guitar cable broken?
❑ Are the TONE or PROGRAM LEVEL (LEVEL/NR/NOTCH) pa-
rameters be turned to a low value?
❑ Is the volume turned down for another effect?
❑ If an expression pedal is connected, is it turned down?
❑ Is the Mute function activated? Refer to "Bypass and Mute" (p.10)
and cancel the Mute function.
