This is a Hughes & Kettner Tube Meister 18. It has only been used about a dozen times, so it's in very good condition. However, please understand that it uses vacuum tubes and other components that may degrade over time. That being said, the vacuum tubes are in good condition, and it produces a beautiful, solid, and thick clean tone, characteristic of Kettner amps. Perceptions may vary, so if you're concerned, you can replace the tubes after purchase. This head is suitable for those looking for a good unit, those wanting to move beyond beginner level, and Kettner enthusiasts. I'm reluctantly selling it because I'm running out of space. I hope it finds a good home. Shipping will be via Mercari, with tracking and insurance for peace of mind. ~Product Description~ This is a 18W full-tube amplifier that can be switched between 1W and 18W.
