Providence FINAL BOOSTER FBT-1 Providence booster. It was used in a switcher, so there are no direct operations. I am selling it because I am replacing equipment. This is a booster/buffer pedal that combines a Vitalizer, which outputs a signal that suppresses changes, deterioration, and noise, with a high-quality full-range booster, the "Final Booster." You will no longer feel the deterioration of sound that occurs when using long cables or connecting multiple effectors. The boost increases the volume while maintaining the original sound, so it doesn't damage the sound of the pedals in the preceding stages. Operation confirmed. Thank you.
