This is a used Jugg Box Staff 060G from Nippon Hammond. It's a legendary Japanese guitar amplifier from the 1970s. This model was beloved by professional guitarists and is often called the "Japanese Mesa/Boogie" because it was developed with influence from the Mesa/Boogie Mark I. It features a unique hybrid structure combining solid-state and vacuum tubes. The preamp uses ICs, while the power amp uses 6L6GC vacuum tubes, successfully combining the advantages of both. The warm, clean sound is exquisite and has been loved by guitarists for many years. While it doesn't distort much due to its characteristics, it has excellent response typical of vacuum tubes and a powerful sound pressure. During the listing, all electrolytic capacitors have been replaced, resulting in a clearer sound. It also has a well-regarded original spring reverb, which adds a beautiful reverberation effect. The volume controls are a bit complicated: Volume 1 only affects INSTRUMENT 1, while Volume 2 affects both INSTRUMENT 1 and INSTRUMENT 2. The vacuum tubes have been replaced with ones branded "FLIP." Judging by their clean appearance, they appear to have been used very little. Operation has been confirmed, and there are no issues with sound output. Output: 60W r.m.s Speaker: Original 30cm x 1 Vacuum Tubes: 6L6GC x 2 Rated Voltage: AC 100V Rated Power Consumption: 90W Dimensions: 470H x 500W x 280D mm Weight: 22Kg Some jacks have not been confirmed as I do not have the necessary connecting equipment. There are many scratches, stains, tears, and dullness. The leather on the handle is frayed, and one of the fasteners appears to have been replaced. Although not specifically designed for it, the speaker grille cloth has been replaced with a coarse linen fabric. Tolex tears have been touched up. Current operation is good, but the volume pots and jacks are from the time of manufacture and may develop crackling or noise over time. Also, this is a used item that is approximately half a century old. There may be other issues that are not fully described. Returns, refunds, and complaints are not accepted, so please purchase with understanding.
