This is the Edition Tube 25th Anniversary, a 20W full-tube vacuum tube guitar amplifier from Hughes & Kettner, released as a limited edition to commemorate their 25th anniversary. It appears to be equipped with Russian-made military NOS (New Old Stock) vacuum tubes. The reverb is an Accutronics spring reverb. It features two channels, clean and lead, and is a 20W tube amp using EL84 x 2 power tubes. It has a Celestion G12T-100 12-inch speaker, and despite its compact size, it delivers ample power and output, making it suitable for both home use and live performances. While Hughes & Kettner has a series of vintage-oriented amps, this one offers a modern, high-gain sound with the deep distortion characteristic of Kettner, making it suitable for drive sounds, HR/HM, hardcore, and heavy metal sounds. It also has reverb. The dimensions are approximately 556 x 480 x 276mm, and it weighs approximately 18.5kg. The original retail price when new was ¥89,250. The condition is also good. There are no major crackling noises or malfunctions, and all controls, operation, and sound output are good and without problems. There is some minor wear and tear, age-related marks, and small scratches on the exterior, but there are no significant damages, large peeling of the leather, or tears in the grille cloth, and it is still in good condition.
