BOSS EH-2 Enhancer. After purchasing, I incorporated it into my board and used it for tonal correction of my amp, but I'm selling it now as 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 struggling with sound creation or those who are not satisfied with their sound in a band ensemble. There are scratches, dirt, discoloration of the knobs, and Velcro on the bottom (for board mounting) due to aging and use, so please check the product images carefully before considering purchasing. Operation has been confirmed. Thank you. Type: Electric Guitar Manufacturer: BOSS #BOSS #EH-2 #Boss #Enhancer #EffectPedal #ToneCorrection
