Sound output confirmed. Comes with the original box. This is a highly valuable effector, as it is no longer in production. This effector is also used on BUMP OF CHICKEN's effector board. I mainly used it as a buffer when recording at home. It was also excellent as a buffer for quadcoretex. I put it on my effector board once or twice a year, so there are some paint chips and blurred lettering in a few places. Please check before purchasing. The FREE THE TONE FINAL BOOSTER is a high-quality booster effector that enhances guitar sound. - Brand: FREE THE TONE - Model Name: FINAL BOOSTER - Product Number: FB-2 - Accessories: Instruction manual, original box - Color: White Thank you for viewing.
