This is an Electro-Harmonix Big Muff. Purchased around 2008-2010. No box, but includes a conversion plug. No scratchiness, and the sound is perfect. Shows some signs of use, but is relatively clean. Those who love music from around the year 2000 will likely enjoy the sound. A wall-like, crushing sound, with feedback and reverb. It would be great to take it to a concert of your favorite band. I used it, inspired by bands like the Red Hot Chili Peppers, The Strokes, and Yura Yura Teikoku, but I'm selling it to organize my equipment. I hope it goes to someone who will use it a lot. Thank you. The Electro-Harmonix BIG MUFF is a guitar effects pedal with Volume, Tone, and Sustain controls. - Model Name: BIG MUFF - Brand: electro-harmonix - Controls: Volume, Tone, Sustain - Connections: Input jack, Output jack - Country of Manufacture: USA
