Please read my profile before purchasing for a smooth transaction. This is a set of guitar effects pedals. It's a set of 3 distortion pedals: an OCD clone, a Tube Screamer clone, and a MI Audio Crunch Box-style clone. "All items have been inspected," so they are almost unused, but please refrain from purchasing if you are sensitive to items being stored at home. These are affordable clone models that are easy to use, even for students. They do not run on batteries, so if you need a power supply, it's available for an additional 1500 yen. How about these for your first pedals? They are cheaper than used BOSS OD-3s, and you can try three different types of pedals.
