Radial Engineering EXTC-SA Guitar Effects Interface

The Radial Engineering EXTC-SA is a versatile interface that allows you to integrate guitar pedals into your pro audio workflow. Acting as both a Reamp box and effects interface, it converts balanced line-level signals to instrument-level for your pedals, then back to balanced line-level for seamless connection with recording interfaces or mixing consoles. Whether you want to add distortion to vocals, fuzz to piano, or flange to strings, the EXTC-SA makes it easy to get creative with your pedalboard in the studio.
