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

Adjusting the tuner 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 AX10B does not remember the tuner calibration setting when powered-off.

Using the expression pedal

You can use the expression pedal to add a pitch one octave lower, and control parameters such as volume, modulation speed, filter, pitch bend, and ambience level.

The expression pedal can control the PRE FX effect OCTAVE, a parameter of the selected MODULATION or AMBIENCE effect (11 types each), or volume. You can choose one of these to be controlled by the expression pedal.

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 volume is selected as the pedal effect, you cannot switch it on/off from the pedal; it will always be on.

1. Operate the expression pedal while you play, and you'll notice how the sound changes accordingly.
   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 use the PEDAL FX button to switch the effect (or volume) that is controlled by the expression pedal. The current assignment is indicated by the color of the LED located at the left of the button. (p.12)

Creating sounds

Creating sounds on the AX10B

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 start from an existing program, select a program that is close to the sound you want, and modify it as necessary. Adjust the amp MID FC/ GAIN,BASS, MIDDLE and TREBLE knobs, and use the VALUE, DEPTH, SPEED, and TAP buttons to adjust the depth and speed etc. of the effects.

If you want to create a sound from scratch, you can (for example) begin by selecting the AMPTYPE. If you turn the PRE FX, MODULATION, and AMBIENCE effects off at this time, you will be able to hear the character of each amp type more clearly. You can switch each effect off by simultaneously pressing its VALUE or DEPTH ▲ and▼ buttons.

When you have decided on an amp type, adjust the MID FC/GAIN, BASS, MIDDLE, TREBLE and VOLUME control knobs.

After you have made your amp settings, you can start adding effects. First are MODULATION and AMBIENCE, located after the amp. Simultaneously press the DEPTH and buttons to switch the effect on. Then turn the MODULATION selector or AMBIENCE selector to choose the desired effect. Use the DEPTH buttons to adjust the effect depth etc. For the modulation effect, you can hold down the FUNCTION button and use the DEPTH buttons to adjust the delay/reverb time. To choose settings for PRE FX, before the amp, turn the PRE FX on, and then use the PRE FX button to select the effect. Use the PRE FX VALUE buttons to adjust the amount of effect. You may wish to temporarily turn off MODULATION and AMBIENCE while adjusting the PRE FX.

Then use the PEDAL FX button to select what you will control from the expression pedal. This button selects the effect (or volume) that will be controlled by the pedal.

If you hear unwanted noise, you can adjust the noise reduction. Hold down the FUNCTION button and turn the NR knob (the right-most knob) to adjust the depth of the noise 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.

Press the PEDAL FX button to select the effect that will be controlled by the pedal. The LED located at the left indicates the effect (or volume) that will be controlled.

ORG: OCTAVE (orange): Octave

RED:MOD (red): The effect selected by MODULATION

GRN:AMB (green): The effect selected by AMBIENCE

OFF: VOLUME (unlit): Volume pedal

If an effect other than OCTAVE is selected for the pre-effect, you cannot select OCTAVE from the

PEDAL FX button. If OCTAVE is selected as the pedal effect, changing the pre-effect to something other than OCTAVE will switch the pedal effect to VOLUME.

Using the pedal to switch the effect on/off

By advancing the pedal all the way forward you can switch the selected PEDAL FX effect on/off. When the effect is on, the LED at the left of the pedal will light. If VOLUME is selected as the PEDAL FX, the LED cannot be turned off.

Setting the minimum value of the volume pedal

If PEDAL FX is set to VOLUME, you can hold down the FUNCTION switch and use the AMBIENCE DEPTH buttons to specify the minimum volume (VOL PEDAL MIN) that will be controlled by the pedal.

Saving the sound of a specific pedal position

You cannot save the sound produced by a specific pedal position. The pedal effect will always modify the sound according to the actual current position of the pedal.

NR (Noise Reduction)

You can adjust the amount of noise reduction by holding down the FUNCTION button and turning the VOLUME (NR) control knob.

Depending on the connected device, excessively high NR settings may cause notes to be cut off. If this happens, lower the level.

Storing a program

When you have created a sound you want to keep, you can write (store) it into one of the 40 user programs (0.1~9.4).

If you switch programs or turn off the power before writing your edited program, the changes you made will be lost.

The program that had been in the writing destination will be overwritten.

1. Press the WRITE button. The program number will blink in the display, and the AX10B will be in "write-ready" mode.
2. Use the program select switches to select where you would like to store the program.
   You cannot write to a preset program (01~94).
3. Press the WRITE button to write the program into the selected program number.

If you decide not to write, press either of the MASTER (CANCEL) buttons to exit write-ready mode (display blinking). You will return to normal operation.
