Fender Blues Junior IV
Fender Blues Junior IV Product Overview by GAK
One of the most-beloved small combo amps in the world, the Blues Junior IV adds modified preamp circuitry, smoother-sounding spring reverb and improved aesthetics that any player is sure to appreciate. A 15-watt favourite in any setting, this amp is ideal for guitarists who need to hit the stage or studio at a moment’s notice with warm tone and versatile features.
The Blues Junior IV includes a 12” Celestion A-Type speaker for well-balanced output with smooth highs, laidback midrange and full, round lows. The modified preamp circuitry has increased fullness, with greater definition and clarity. The onboard spring reverb has been modified to add smoothness, so you still get rich, shimmering tone, no matter how much reverb you use.
The updated aesthetics include improved control panel texture and graphics, ivory pointer knobs, steel-reinforced strap handle and lightly- aged silver grille cloth, giving it the unmistakable look and vibe you can only get from a Fender amp. Reliable, flexible and pedal-friendly, the Blues Junior IV is an ideal addition to any electric guitarist’s amp collection.
The EL-84 output tubes provide fat mid tones while warmth is provided by the 12AX7 preamp tube overdrive. There is also real spring reverb.

Excellent amp at relatively low cost. Amazing power for size and also good and responsive at low volume
Finally decided to replace my old green board Blues Junior (including billm mods) with a new version IV. Fender’s improvements to tone and reverb are excellent, though I would have preferred an adjustable bias for the power valves. My first observation was an unusual mix of Groove Tubes in the preamp (V1 JJ, V2 Sovtek and Shuguang for the V3 PI) so I installed my own set of preferred OEM valves from years of research and ‘tube rollling’. The Groove Tubes sounded much better - smooth, rich overall tone and a more punchy bass response, and the output valves are perfectly balanced. I will pay the extra and replace with the same Groove Tubes in the future. Probably worth noting that Fender still ship their Amps to the UK set to the EU harmonised mains voltage of 230V, when the mains transformer has a dedicated 240V tap. Overall very impressed with the new version and would highly recommend it.
Very Pleased my Fender Blues Junior IV amp that I purchased from G. A. & K., the service I received from them was superb the amp arrived in perfect condition & on time I cannot thank them enough. I already have a very old Fender Amp but the Blues Junior is really ideal for me, as I generally only play at home nowadays and with my pedals I can achieve a great sound at lower volumes, however if I do a Gig the amp has plenty in store to deliver in the local pubs & clubs when open.
Great amp. Everyone says they are good and they are. I had a Fender Champ before, but this is different league.
15 watts? You're kidding me! This thing is loud, takes pedals well and is an overall improvement on the Blues Junior III. I would prefer the speaker grille to be covered in the original bright fabric as this looks like it's been in a smoke filled room for several years, but it still gets 5 stars.
