Name Explanation
INPUT jack

Connect your guitar here.

* To prevent malfunction and equipment failure, always turn down the volume, and turn off all the units before making any connections.

[GAIN] knob Adjusts the distortion of the amp.
[TYPE] switch Selects the amp type.
BROWN A lead sound with an edge inherited from the BOSS WAZA brown sound.
CRUNCH A fat crunch sound that responds to the nuances of your picking.
CLEAN A clean and natural sound.
[VARIATION] button
VARIATION indicator

When the [VARIATION] button is switched on (the VARIATION indicator lights up), the sound switches to the variation sound that's selected with the [TYPE] switch.

When the [TYPE] switch is set to "CLEAN", you get a sound that's suitable for acoustic-electric guitars or bass guitars.

[VOLUME] knob Adjusts the volume.
EQUALIZER You can use the tone stack-type three-band equalizer for creating authentic sounds.
[BASS] knob Adjusts the volume of the low-frequency range.
[MIDDLE] knob Adjusts the volume of the middle-frequency range.
[TREBLE] knob Adjusts the volume of the high-frequency range.
EFFECTS A variety of effects are available.
[MOD/FX] knob

Selects the effect you want to use.

Use the knob to adjust how much the effects are applied, within the given range for each effect on the knob.

CHO Chorus
PHASE Phaser
TREM Tremolo
T.WAH Touch wah
DEF Defretter
SYNTH Synth (*1)
OCT Octave
(*1)
  • The effect may not sound the way you expect when you play chords (two or more notes at the same time), because of how it analyzes the pitch. Be sure to mute all the other strings and play only one note at a time.
  • When you want to play the next string while another note is still playing, mute the previous sound and then play the next one with a clear attack. If the unit cannot detect the attack, the effect may not sound correct.
  • The sensitivity may vary according to the setting of the TONE knob on your guitar/bass and the pickup type.
  • When you turn down the [VOLUME] knob with the [TYPE] switch set to "BROWN", this may make pitch analysis difficult, and the note you play might not be detected accurately. Raise the [VOLUME] knob setting in this case.
[REV/DLY] knob Uses a reverb/delay effect to produce a sense of sonic spaciousness.
REV Reverb
SPRING Spring reverb
DLY Delay
DLY+REV Delay + Reverb

  3. When you have finished tuning, press the [TUNER/ ] button again.
    The TUNER () indicator blinks for about one second.

Troubleshooting

Problem What to check and do
The unit doesn't charge even when I connect it to a USB AC adaptor. Check whether the USB AC adaptor can deliver at least 5 V/2 A of power output.
The unit doesn't run for very long on battery power (while not supplied power from a USB AC adaptor).

The battery may have been excessively discharged.
Try doing a "refresh recharge".

How to perform a refresh recharge

  1. Turn this unit off.
  2. Charge the unit with a commercially available USB AC adaptor (at least 5 V/2 A).
  3. Disconnect the USB AC adaptor after charging is complete.
  4. Turn on this unit and then let it run on battery power all the way until fully discharged.
  5. Repeat steps 1–4 several times.

* The battery's performance may not fully recover after you recharge the battery only once following excessive discharge. Although the battery performance does recover after refresh recharging, this does not restore the battery's original performance.

"KATANA-MINI X" is not shown on the display of the mobile device you want to pair with this unit.

However, it does appear on other mobile devices.

Cycle the power of the mobile device you want to use.
