I removed the item that was attached to the guitar. There are no issues with its operation. The main unit and sponge are included. The lead wire is approximately 46cm long. It reproduces the airy top end, tight bass, and well-balanced midrange, as well as the overtones of a well-preserved original PAF. Its excellent tonal balance has consistently received high praise from players. The intentionally unbalanced coils provide tightness in the low frequencies across all tones, and because it contains many harmonic components, a smooth and flowing sound can be obtained even with each individual note picked. The moderately demagnetized magnet creates a realistic vintage sound that even captures the effects of aging.
