I am selling this important equipment due to financial constraints. This is a Billy Sheehan model BB714BS, released in October 2008. Unlike the Attitude model, this is based on the BB series, and the woofer pickup allows for powerful low-end output. I purchased this used about 5 years ago and used it as a sub-bass. There are minor scratches, body dents, scuffs, scratches around the jack, a missing truss rod cover, and dullness on the metal parts. Please refer to the photos for details. The frets have about 80% life remaining, the neck is currently straight, and the truss rod has room in both directions. The action is set low for easy playing. Today, I have tested the sound, truss rod, and all functions. The strings are old. There are also three modifications: ① The original split-coil PU has been replaced with a Nordstrand np4 (the hole in the PU case has been adjusted because the pole piece width of the original PU did not fit). This is perfect for those who prefer a vintage sound. The NP4 pickup cover has a self-made pickguard made of acrylic board that is fixed with adhesive. This is easier to rest your thumb on when playing with a 3-finger technique. ② A Providence Vitalizer has been installed (this device converts passive/high-impedance signals to low-impedance without coloring them, sending out a signal that is resistant to degradation). ③ A HIP SHOT extender has been modified and installed. The color is slightly different from the original because it was only available in black. Due to the modifications, I will not accept any claims after purchase. Thank you for your understanding. ※ Due to the effects of the three modifications, the instrument has a wide sound range. The discontinued Billy Sheehan model is currently difficult to obtain. I am selling it in its modified state, so if you want to revert it to its original state, please do so yourself after purchase. Please contact me with any questions before purchasing. Accessories: Dedicated soft gig case, original pickups, original 4-string tuners, and two sets of Rotosound BS66 strings. Body: Alder Neck: Maple Fingerboard: Rosewood For more detailed specifications, please refer to the YAMAHA official website. Note: Shipping costs will be within 5,000 yen, depending on the region.
