Roland Micro Cube guitar amps can liven up musician gatherings without crowding the room. The portable, battery-powered amps offer several built-in effects and amplifier simulators to bring out your inner Jimi Hendrix.

Opening the amp can be done to replace the 4-inch speaker if it becomes worn out or broken, or to repair loose internal connections. Easiest access is gained through the front grille, but the electronic chassis can be removed if necessary.

Skill level:

Things you need

  • Phillips screwdriver
  • Thin blade or putty knife

  1. 1

    Disconnect the power supply and remove batteries from the amp. Disconnect any cables, headphones or other connections.

  2. 2

    Remove the screws located at the bottom left, and top and bottom right sides of the speaker grille.

  3. 3

    Lift grille to reveal speaker. To replace speaker, remove four screws holding speaker and carefully lift from case. Disconnect wires and place speaker aside.

    Connect wires to new speaker, insert and replace screws.

  1. 1

    Remove the seven screws on the back panel, and the three large screws on the top of the case to remove the electronics.

  2. 2

    Insert a thin blade or putty knife between the top of the metal electronic chassis and the case to cut through the double-sided foam tape holding it in place.

  3. 3

    Carefully remove electronic chassis. Tighten or adjust any loose connections.

  4. 4

    Place double-sided tape around edges of top fold on chassis, and place back into case. Replace and tighten screws to reassemble.

Tips and warnings

  • Place screws on a magnetic holder or in a small container to avoid losing any.
  • Choose a 4-ohm, high-fidelity speaker for the replacement. Replacement car stereo speakers can be used.
  • Only remove electronic chassis if necessary--diss-assembly can void warranties.
  • Do not use excessive force to pry apart the chassis.
  • Tighten all screws to avoid having rattles or buzzing when using amp.
