Critic Reviews

Fender Blues Junior III review - The Blogging Musician

adamharkus.com

The Fender Blues Junior III offers a clean, punchy tone and compact portability, making it a great choice for musicians who prioritize simplicity and pedal-based effects. While it excels in delivering classic Fender cleans, its overdrive leaves much to be desired, falling short of more robust options like Marshall or Cornford amps. Build quality is a mixed bag, with some components feeling cheap, and at £470, it lacks features like a cover or footswitch. Despite these drawbacks, its practical design and sound quality can satisfy players looking for a straightforward gigging amp.

Fender Blues Junior III Review

justguitaramps.com

The Fender Blues Junior III impresses with its clean, fat Fender tones in a compact design. Packing a surprising punch for a 15-watt amp, it’s pedal-friendly and excels in both clean and overdrive settings. Ideal for small gigs, its brightness suits humbuckers but may need tone adjustments for single-coils. Improvements over previous versions, like the readable controls, enhance its appeal. Despite breaking up at higher volumes, the Blues Junior III remains an outstanding value for its price.

Little amp with great sound!

I played in a band with a friend who then had a bad illness and died so he left me this beautiful amp. I was playing with a reverb deluxe 65 before but the blues junior is more hot and present so I sold the reverb deluxe and now I'm playing with it. My amp has a bigger speaker and a special kit that improve brightness on the sound. It's also easy to transport for the gigs and it provide all the sound I need, little amp, great result. Thank you Sergio.

Preferred Settings + Usage:

I don't use the reverb of the amp as I have a verbzilla pedal which is fab! I use treble 10 / medium 5 / bass 3. Master 5 / volume 10, then I use the guitar volume to have the appropriate sound otherwise a wall of feedback comes out!

If it only had a better handle

The amp sounds great, is very versatile and is more resistant than i thought to moisture environments. The rubber "plasticky" just seems to be weak for the weight of the combo. I always end up picking it up from the bottom to prevent using the handle. I always feel it can break at any time. Other than that, it's probably on of the best combo's out there. Best for soloing guitar it can be used and well used as well for rhythm guitarists. Also, the volume and master knobs allow for good crunch sounds at low volumes or enough power to fill a small/medium venue on it's own.

My Modded Blues Junior

I have played many of these amps, they do have a certain British tone to them. I preferred to modify mine with 6V6 tubes, a 12AT7 driver tube, and low gain 12AX7 in the #1 position. Also, I changed out the 12" speaker to a 10" and an 8" speaker on the baffle, to allow more clarity in the notes. With these mods, the amp sounds closer to a mini Super Reverb, and has just enough power for small gigs.

yeah, EL84s, even in fixed bias? unfender! prior to this amp there was just the short lived EL84 blonde tremoluxes that mostly melted down... for some reason the oddball marshalls with 6V63s sound british, but the blues jr is way un-American stock

Packs Great Tones and Power!

Great amp value for your money. These things are good stock, but can be hotrodded and customized in a many number of ways - which is something I really dig about them.

That’s awesome! Same here - have a buddy who modded out one of his that I’ve tried and is nice but stock out of the box is great!

Baby Hot-Rod

Affordable Hot-Rod sound in a slightly more manageable size. Sounds amazing with pedals, screaming tube overdrive when driven, although clean sound is great too. Includes a lovely sounding spring reverb.

little monster

I upgraded mine with a cannabis rex speaker and it sounds so much better. The stock speaker was to ice picky for me but the CR made it perfect. This is my go to live amp, it is portable but loud enough for anywhere i play.

amazing sounding amp

first amp I toured with, amazing tone. loud if you need it, quiet when you need it as well. Great sound when overdriven as well. My only complaint (which isn't really a complaint) is the top controls as opposed to my preferred front facing controls.

Awesome all around

This is the perfect size! The clean tones are spectacular, and it can get really dirty. I love the master/drive volume knobs; I can crank it and get some sweet tube distortion while still keeping things at a reasonable volume!
