Features: The F-5T pickup is great for tuning on the move or on-stage. It features a note function for manual string tuning as well as an auto mode which will detect the string you are tuning automatically. As well as giving your guitar a modern look, the backlight LCD ensures visibility in all lighting conditions. The built-in tuner will be preferable over a clip-on tuner in noisy conditions. The indicators will ensure your guitar will always be perfectly in tune and within 10 cents accuracy. The three LED lights will show if the string is flat, sharp or in-tune. Great accessory for electric acoustic and classic guitars.
