Do not play two or more strings simultaneously when tuning.
3. Tune the string approximately so that the correct note name is shown in the display.
4. Fine-tune the string so that only the middle LED of the PRE FX (TUNER) section is lit.

When the note name is A# Too low

Too high

Correct tuning

1. When you have finished tuning, press the UP or DOWN program select switch to return to normal operation.

Adjusting the tuning calibration

When you turn on the power, middle A is set to a reference frequency of 440Hz . If desired, you can adjust (calibrate) this reference pitch.

1. While the tuner is activated, use the VALUE (CALIB) buttons to adjust the calibration. The range is 438 - 445Hz . When you adjust the value, the display will show the lower two digits of the calibration frequency (e.g., "41" for 441Hz ).
   The AX10A does not remember the tuner calibration setting when powered-off.

Using the expression pedal

You can use the expression pedal to control the volume, ambience level, chorus depth, or notch filter frequency.

The effect controlled by the pedal can be one of the eleven AMBIENCE effects, CHORUS, NOTCH, or volume. You can use the pedal to control one of these.

Using the expression pedal

1. Select a program for which the PEDAL LED (located at the upper left of the expression pedal) is lit.

If you have selected a program for which the PEDAL LED is lit, you can use the expression pedal to control a pedal effect.

Even for programs for which the PEDAL LED is not lit, you can advance the pedal all the way to switch it on (the PEDAL LED will light).

If the pedal is assigned to volume or NOTCH, you can't switch the effect on/off by advancing the pedal.

1. Operate the expression pedal while you play. The output sound will change as you move the pedal up and down. If you've assigned PEDAL FX to NOTCH, you'll be able to suppress acoustic feedback by operating the pedal when it occurs; move the pedal to the point at which the feedback disappears. If you are not experiencing acoustic feedback, we recommend that you set the pedal to the minimum position to turn off the effect.
   Do not apply excessive force to the expression pedal. Before you begin using the expression pedal, you should determine the amount of force that is needed to make the PEDAL LED light or to control the effect, and use only the necessary amount of force.
   TIPS You can press the PEDAL FX button to change the effect or volume being controlled by the expression pedal. The color of the LED located at the left of the pedal indicates the assignment (p.12). Page 12 also explains how you can save a sound you created by operating the pedal.

Creating sounds

Creating sounds on the AX10A

You can create sounds in one of two ways; you can edit an existing preset program or user program, or you can create a sound "from scratch."

If you want to create a sound that's based on an existing program, select the program that's closest to what you have in mind, and make the desired changes. Adjust the BASS, MID FC, MIDDLE, and TREBLE tone control knobs, and use the VALUE, DEPTH, and TAP buttons to adjust the depth of each effect.

If you want to create a sound from scratch, one method is to start by choosing a MIC & BODY TYPE.

When doing so, leaving the PRE FX and AMB & CHORUS effects turned off will make it easier for you to hear the differences between the various mic or body models. Simultaneously press both VALUE or DEPTH and buttons to turn the corresponding effect on/off.

When you've decided on a mic & body type, adjust the tone control knobs BASS, MID FC, MIDDLE, TREBLE, and LEVEL as desired.

When you've finished making the mic & body settings, you can add effects. AMB & CHORUS is located after the mic & body section. Simultaneously press both DEPTH and buttons to turn on the effect, and turn the AMB & CHORUS selector to choose the effect you want to use. Then use the DEPTH buttons to adjust the depth of the effect. For the chorus effect, you can hold down the FUNCTION button and use the DEPTH buttons to adjust the effect depth. You can adjust the delay/reverb time of the ambience effect by pressing the TAP button at the desired timing interval.

Next you can adjust the PRE FX, which is located in front of the mic & body section. Turn the effect on, and then press the PRE FX button to select an effect. Use the PRE FX VALUE buttons to adjust the amount of effect. You may want to turn AMB & CHORUS temporarily off while adjusting the PRE FX.

Finally, use the PEDAL FX button to specify what the expression pedal will control. The pedal assignment (effect or volume) will change each time you press the button.

If you hear unwanted noise, you can adjust the noise reduction (p.12). Hold down the FUNCTION button and turn the tone control NR knob (the knob at the far right) to adjust the amount of reduction.

Finally, when you have come up with a sound you like, you should write (store) it into memory. If you switch to a different program or turn off the power without writing your new program, it will be lost.

Some effect settings may produce unwanted distortion. If this happens, lower the VOLUME knob.
