Boss Chromatic Tuner TU-3

Absolute waste of $140 – I purchased a Boss TU-3 tuner in December 2019 and I can honestly say this would have to be the worst tuner I have ever owned. Every time I go to use it the battery is dead. I never leave the lead plugged in and I would be lucky to use it twice and it's dead again. Rather than sell this junk to someone else I'll be sending it back to Boss and i'll buy another brand!
