ship from Japan The POLYTUNE 3 MINI features a built-in BONAFIDE BUFFER that reduces signal degradation and provides an extremely high signal-to-noise ratio. With the POLYTUNE 3 NOIR, you'll never go too far with your arming again. The always-on mode allows you to check the pitch while you are arming to ensure that you are arming at the correct pitch. Buffered bypass mode and true bypass mode can be switched easily. DIP switches on the outside of the enclosure allow you to easily switch between buffered and true bypass. Whether in direct sunlight or under large lighting fixtures, POLYTUNE 3's bright display offers high visibility. The powerful LEDs activate all at once, so you don't have to look for the display anymore.
