This is the FORCE, a masterpiece booster from JT Products. It's an excellent booster that boosts the signal without compromising the original sound. When used with single-coil pickups, it adds a tight, powerful low-end, giving them character. If you turn the GAIN past 4 o'clock, it can also be used as an overdrive (fuzz). (Bonus?) While it's difficult to control the amount of distortion, I loved the sound. It also has low noise. Velcro is attached to the back. Available for immediate purchase.
