The Boss TU-1000 is one of the largest tuner pedals ever made, measuring an impressive 414mm wide. Launched at Winter NAMM 2009, it aimed to offer visibility and ease of use on stage, solving issues commonly raised with smaller tuner pedals. While it was criticized for its size, its large display benefited visually impaired guitarists, garnering a niche user base who appreciated its clarity. Despite having two tuning modes and the ability to handle open and drop tunings, the TU-1000 became more famous for sparking memes than for its sales success. Initially priced at $299, its retail value plummeted to as low as $39 by 2015, yet it continues to resonate with some players who appreciate its unique attributes.
