The Fender Blues Junior III is an all-valve 15w combo amp that is small enough to be easily portable. It’s good for studio or rehearsal, and can also be used for gigs. It’s known for warm rich tone, and features Reverb and also a Fat Switch to give you extra low end boost. It’s single channel and the clean sound can be easily mixed with the drive to give a lightly-driven tone without having to crank it up and use an attenuator. The Blues Junior is part of the Hot Rod series and has a 12 inch Eminence speaker, three 12AX7 preamp valves and two EL-84 Groove Tube power amp valves.
