The C20 by Swiff Audio improves on the incredibly popular and groundbreakingly tiny C10, with an upgraded and very sleek metal enclosure, footswitch, and robust enclosure. The original C10 had a tiny footprint, and the C20 doesn’t waste any space either, taking up just 41 X 41mm of your pedalboard real estate! This is ideal for crowded boards, and with the mute-tuning feature, it can also be simply used as a true-bypass mute switch to kill your signal – you won’t find one smaller! The C20 also offers a super bright LED display with clear colour tuning indication that can be seen under any stage lights, and even includes switchable long-life Velcro or non-slip silicone bottom bracing. The Swiff C20 has an easily adjustable A4 tuning range that can be calibrated with a double-stomp on the footswitch, allowing you to manually calibrate between 430Hz-449Hz, and it uses a standard 9V center-negative power supply.
