A 1950s Gibson BR-9 Combo in Good vintage condition. 

FROM HISTORY OF GIBSON AMPLIFIERS:

War-time restrictions of components and hardware forced Gibson to halt manufacturing of electric guitars and amplifiers during World War II. Gibson began production again in 1946, employing Chicago-based electronic design company Barnes & Reinecke to design a new amplifier line. The new amps included the Ultratone BR-1, BR-3, BR-4, BR-6 and BR-9 models, with 10 to 18 watts of power. Volume and tone controls were featured on all models, except the smaller BR-6 and BR-9 amplifiers. The BR amplifiers were produced until 1954 and were discontinued to take advantage of more popular features and newer technology.
