Thank you for viewing. The JuggBox JBX-jr30 is a hybrid amplifier that uses a 12AX7 vacuum tube in the preamp section. Thanks to the vacuum tube preamp, it produces a rich, warm sound. There are some minor scratches on the front grill, but I have confirmed that it powers on, produces sound, and the reverb works properly. As it is old equipment, there may be some slight crackling, but I think the condition is good for a vintage item. It's a masterpiece with an excellent design, so it might be good for your collection. Please consider it.
