If you’ve ever fancied experimenting with your S-type guitar’s wiring but don’t fancy burning your fingers, HyperSwitch is your solution. This five-way, 9v battery-powered smart switch is wired into your guitar once, replacing your original pickup switch, then connects to a mobile app via Bluetooth where you can endlessly reconfigure and recall wiring presets. With options for coil-splitting, reverse polarity and more, it can also change the taper of your guitar’s tone controls. The HyperSwitch works with most passive guitar pickups, costing £209, and should be shipping by the time you read this.
