Introduction

This guide walks you through the process of removing the faceplate from the Boss CE-300 Super Chorus (model CE-300). The CE-300 is a vintage effects processor known for its warm, analog chorus sound. If the faceplate is cracked, obstructs control knobs, or affects usability, this guide will help you detach it safely for repair or replacement.

The faceplate serves as both a protective cover and a housing for control dials, switches, and jacks. Issues such as damaged knobs, loose switches, or visible wear might make replacement necessary. Before starting, set up a clean workspace and gather the required tools, including a Phillips #2 screwdriver, 11mm wrench, and 14mm wrench.

Handle the device with care, especially around clips and cables connecting the faceplate to the internal components. Avoid using metal tools on sensitive parts to prevent damage. This guide is beginner-friendly, so no advanced skills are needed—just follow the steps closely.
