Introduction
This guide provides instructions for replacing faulty switches in the Boss CE-300 Super Chorus, a renowned analog chorus effects processor used by musicians to produce rich, dynamic sounds. The switches control various features of the device, including muting and effect adjustments. If the switches are unresponsive, loose, or show inconsistent functionality, replacing them can restore the unit to optimal performance.
The replacement process involves accessing the device’s internal components, which requires disassembling the faceplate and bottom panel. You will also need to desolder the faulty switches from the circuit board and solder the new ones in place. The guide assumes you have basic soldering experience and access to tools such as a Phillips #2 screwdriver, 11mm and 14mm wrenches, and a soldering iron.
Care should be taken when handling internal components, especially during desoldering, to avoid damaging the circuit board or other sensitive parts. Follow this guide step-by-step to ensure a successful replacement.
