I'm selling this because I bought it a few months ago but ended up using compact effects pedals more. Manufacturer's product site ⇩ https://www.boss.info/jp/products/gt-1/ It works perfectly with no noise. I've used it at home and in the studio, and I've tried various sounds, all of which came out beautifully. Playback of external audio sources through the Aux input was also problem-free. The body is black, so there are some minor scratches, but these are from normal use. Included: BOSS adapter PSA-100S, which I bought new to use with this product.
