Product Overview
The Boss TU 3 Chromatic Tuner Pedal is a high quality guitar and bass tuner pedal designed to provide accurate tuning in any environment. It features a 21 segment LED meter that provides excellent visibility, even in outdoor settings. The TU 3 also includes support for drop tuning, allowing you to easily switch between different tunings. The pedal runs on a 9V battery and has an item weight of just 0.53 grams, making it highly portable.
The first thing I noticed about the TU 3 was its accuracy. The 21 segment LED meter provides easy to read and accurate tuning results every time. As someone who has used many different tuners in the past, I found the accuracy of the TU 3 to be outstanding. I was also very impressed with the drop tuning support, as this is something that many other pedals I ve used do not offer.
I was also impressed with how easy it is to use the TU 3. All you have to do is plug your instrument into the pedal and strum each string until it s in tune. The LED meter will display the correct pitch for each string, making it easy to tell if you need to adjust your tuning or not. It also features an auto off function which can be set so that the pedal turns itself off after a certain amount of time to save battery life.

The size of the TU 3 is also impressive it measures just 9 x 4 x 6 inches and weighs only 0.53 grams, making it highly portable and convenient for on the go musicians who want to keep their instruments in tune while travelling.
Overall I would highly recommend this product for anyone looking for an accurate and reliable guitar or bass tuner pedal that is both easy to use and portable. Whether you re an experienced player or just starting out, the Boss TU 3 Chromatic Tuner Pedal should be able to meet your needs. It provides quick, accurate tuning results and supports multiple tunings, making it perfect for any situation where you need quick access to a reliable tuner pedal.
