Here's a "Bass Buddy" from Phil Jones Bass (PJB), a staple tool for bassists. I'm selling it to clear out my gear. It's renowned not only as a high-quality preamp suitable for professional settings but also as an excellent headphone amplifier. With an AUX IN (external input), it's perfect for practicing at home while playing along with music from your smartphone or other devices. 【Product Contents】 Body only. *AC adapter, original box, and instruction manual are not included. 【Condition】 Functionality: Tested and confirmed to be working properly with my own batteries (2 x 9V batteries). There are no noticeable crackles in any of the knobs. Appearance: There are minor scratches from use, but no major dents / It shows signs of use commensurate with age. About the AC adapter: It is not included due to being lost, but it can be powered by batteries, so you can use it immediately in places without power, such as studios or outdoors. (For long-term use at home, we recommend preparing a compatible universal adapter or using rechargeable batteries.) 【Shipping and Packaging】 It will be carefully packaged in a waterproof OPP bag and bubble wrap, then shipped in a cardboard box. We will ship via anonymous delivery, and will process the shipment within [24 hours] as much as possible.
