BOSS VE-20 VOCAL PROCESSOR Vocal Effects Pedal Effect Type: Chorus, etc. 6 rechargeable batteries Charger included Used for about 70 hours Power adapter not included. Has not been used with foot pedals. As can be seen in the second photo, there is a stain in one place. It did not come off with a wet cloth, but it does not affect use. I was using it as an effects pedal for saxophone, but I am selling it because I switched to wireless. The sound is really good. No returns or exchanges, please.
