【Product】 Phil Jones Bass Double Four BG-75 PJB X4 Superior Compatibility, Phil Jones Includes dedicated bag This is a two-speaker model from PJB, which boasts outstanding sound quality in small, tabletop amplifiers. I currently use a Darkglass head amp in the office and a PJB X4C at home, and I bought this to replace my home amp. The previous owner also said it was "like new," so it's in excellent condition. Includes a separately sold dedicated case. It's ultra-compact, about 30x20cm, and I've tried various amps like the YAMAHA thr-10, NUX mighty bass, and Possitvie Grid, but I settled on PJB. When it comes to bass sound, it's of outstanding high quality. It has overwhelmingly smooth and deep bass, and it prioritizes the original sound. It has far more power than the X4C and is suitable for outdoor performances, and it can also be used for recording via the output jack. It's basically considered a superior compatible model to the X4. However, I can't turn up the volume that much at home, and the X4C is sufficient... I can't fully utilize its potential, so I'm reluctantly selling it. ※ Please only ask questions or make comments that are essential to your purchase decision. ※ We cannot respond to any issues already mentioned in the profile. 【Condition】 ・Excellent condition, very clean. ※ "Excellent condition" is based on my subjective judgment that there are minor scratches, scuffs, and dirt, so please understand that there may be some signs of use. ※ Boxes, manuals, cases, etc., are not included unless specified in the photos or text. 【Other】 ※ We do not accept returns except for major initial defects, such as a difference in image.
