Limited edition. Selling because I need money and am decluttering. I remember all the guitarists around me scrambling to put this on their boards because they said it made the sound thicker just by connecting it... This is a limited color model with a silver body and cream-colored knobs, a good-looking masterpiece. Please note that Velcro is attached to the back. The RC Booster is a high-quality guitar effects pedal designed to improve sound quality. - Model: RC Booster - Controls: Volume, Tone, Boost - Input/Output Jacks: 1/4 inch jacks - Appearance: Metal case Thank you for looking.
