The Blues Junior III All-tube Combo Amplifier. Featuring a Preamp section fitted with 3x 12AX7's and a Power section outfitted with 2x EL84 Power Tubes the Blues Junior is a great all around gigging/practice amp for those seeking portability. The signature Fender clean tones are certainly present on this amp, but the Blues Junior also makes an excellent platform for Pedals and Effects Units giving you a clean palette to experiment endlessly. You'd be hard-pressed to find a more straightforward workhorse amp, that's light weight and easy to take to jams or open mic nights. At 15-watts the Blues Jr. will put out plenty of headroom to play along with a drummer or full band.
