Introduzione

Use this guide to replace the volume potentiometer of your OP-Z.
In case the defect was caused by a drop then the volume knob was probably damaged too. This guide will also show how to replace the knob which can be purchased separately.

  1. Unlock the four rubber feet by turning them 90° counterclockwise using your thumb or finger tip. There is a tiny mark on every foot facing the bottom edge of the OP-Z. After turning them they should face towards the short edge where the on/off switch is. There is a tiny mark on every foot facing the bottom edge of the OP-Z.
