This is the BOSS EH-2 Enhancer. I used it for tonal correction in my guitar sound shaping, but I'm selling it because I don't use it as often anymore. It's an effects pedal that doesn't drastically change the sound, but I found it useful to have in various situations. Please consider purchasing it with the understanding that there are scratches and dirt from use. Thank you. Made in Taiwan #BOSS #EffectsPedal #Enhancer Type...Electric Guitar Manufacturer...BOSS
