Fender® Blues Jr Tube Set

Tube Set for Fender® Blues Jr.

Blue Jr is perhaps the most common Fender amp today. It is compact, portable, and sounds great. We find Blues Jr to be plenty loud despite having only 15W output.

We have assembled this tube set with TungSol 12AX7 and JJ EL84. These tubes are reliable, sounds great, and a step up from the factory tubes.

TungSol 12AX7 has that vintage rock and blues tone, and JJ EL84 adds a pleasant chime and sparkle to it. Combined, they complement and enhance the classic Fender tone.

Blue Jr has no bias adjustment, and the amp needs EL84 tubes that bias within a specific range. We will select the tubes in the right range so it will be plug and play.
