Thank you very much for viewing. This is the FAT RAT by PRO co. I love RATs and have collected and used many, including the BLACK FACE, but I think this FAT RAT is quite good, including its usability. By combining the two switches on top, you can completely change the nuance, and the amp-like distortion that rounds out the slight harshness when in MOSFET mode is easy to use even for those who don't like RATs. The robustness of the unit and the fact that you don't have to worry about the deterioration of internal electronic parts, unlike vintage ones, are also recommended points. I am selling it to change equipment. Thank you.
