This is the BOSS EH-2 Enhancer. After purchasing it, I used it on my board and for sound quality correction with my amp, but I'm selling it now because I no longer use it. To be honest, it's not an effect pedal that drastically changes the sound, but depending on the settings, it can improve the clarity of the sound and make the guitar stand out, making it a pedal for professionals. Personally, I liked this effect pedal so much that I bought several of the same model, so I hope it will help guitarists who are struggling with their sound or those who are not satisfied with their sound in a band ensemble. There are some minor scratches and dirt due to age and use, but it's in relatively good condition. Operation has been confirmed. Thank you.
