Big Muff Ringer Shirt
Promotional ringer shirt given out to musicians by Big Muff pedals in the 90s. Big Muff is an iconic guitar pedal, used by lots of guitarists, especially in indie, grunge and and garage rock. If that logo looks familiar, it's because Mudhoney used their font design for their most popular T-shirt, because they loved the pedal so much. That Mudhoney shirt was famously worn by Kurt Cobain, and is a classic vintage T-shirt all thanks to that Big Muff design.
