[3] Notes on disassembly and assembly Tone Knob ASSY
[3-1] Disassembly
• To remove the Tone Knob ASSY (BASS,
TREBLE, BALANCE), operate them at the
center position.
Otherwise, the force to remove the Tone
Knob ASSY breaks the encoder, and
center-click feeling is lost.
[3-2] Assembly
• Also to attach the Tone Knob ASSY, operate
them at the center position.
• Before assembling them, turn the Encoder
Axis by hand, and confirm that you feel
center-click.
If you don't feel it, replace the part.
