Sweetwater-exclusive Blues Junior with Cannabis Rex Speaker

One look at this Sweetwater-exclusive Blues Junior IV Fender Special Run, and it's clear that you've found something special. Clothed in eye-popping Western Tolex, this 15-watt, 1 x 12" combo features a conveniently giggable size, pedal-friendly character, and ideal volume that's guaranteed to make you smile. Add to that a tweaked preamp for a larger tonality and silky-smooth reverb, and you'll quickly understand why the Blues Junior IV is sure to become a legend of its own. On top of that, the FSR version of this amplifier comes loaded with an Eminence Cannabis Rex speaker, renowned for its powerful American-style tone. With this Blues Junior IV FSR, boutique tone is well within your reach — plug in and seize it!

A truly legendary combo

Players of all styles and genres have been leaning on Fender Blues Junior all-tube combo amplifiers for years. Their ability to coax American cleans and thick drive from their EL84 power sections allows them to fit within any rig. They are also incredible platforms for players who utilize effects to achieve their tones. But perhaps the most attractive thing about the Fender Blues Junior IV FSR and previous models is the way Fender crammed the perfect amount of power into a combo that is affordable, lightweight, compact, and extremely easy to gig with.

Familiar tone with a bigger attitude

The Blues Junior has always been known for great tones. Yet to make the Junior IV stand out from previous iterations of the model, Fender tweaked the preamp to deliver a fuller sound that is far in excess of the amplifier's compact dimensions. As you turn the amplifier up, you'll notice the lows stay full, the mids can be as assertive or as mellow as you need, and the top still sings with the familiar American-voiced chime. Not only that, but you'll control it all with the same easy-to-navigate top panel controls as before. Great sounding and simple to use. Can't ask for more than that.

A few added tonal sweeteners

The preamp tweaks in the Blues Junior IV already take it into boutique-tone territory. But Fender didn't stop there. They also worked on the amplifier's spring reverb circuit, smoothing out its tone. This allows you to crank it into surfy territory without losing any tonal detail. Beyond that, the Fender Special Run version is loaded with an Eminence Cannabis Rex speaker. The Cannabis Rex gives you classic American tone with a big bottom end — a powerful, chunky tone that's perfect for blues, country, rock, and jazz. You'll love how touch-sensitive the response is, with excellent sustain too. This Sweetwater-exclusive IV is the Blues Junior you've always wanted.

Unreal

First off I need to thank my great Sweetwater Engineer Mike Singer, for making this all happen and making me extremely happy for pointing me in the right direction to purchase this amp. Thank you Mike for all you do, Sweetwater is lucky to have you. I want to save all you that might read this a lot of time because I can literally go on for hours how great this amp is and why it's so great. Please believe me when I tell you that i have had many, many amps being both tube and solid state. From Vox, Marshall, Fender, Boss, Blackstar, Peavey, etc,etc. You name it I have had them or tried them out and not one of them can compare to my new Fender Blues Jr Western Tolex. Wow this is a tonal beast that gives me the tones that I crave. I can dial in any type of music for the simple fact that it takes pedals like a dream. So far I dont need pedals because right out of the box it gives me so much more than I could ever expect. The speaker they decided to use when they made this amp exclusive for Sweetwater could not be a better match. From reviews and listening to other Blues jr Amps they nailed it by using the Eminence Cannabis Rex speaker. Once again thank you Mike and Sweetwater for a great product and kindness as usual. I do have one complaint, add more candy to the packets you give out, Hahaha...

Best fender amp under a 1000

Very very good amp for the money. Originally, the Blues jr. for me has never been an amp I wanted to buy. I've played a lot of fender amps to know that you need to dish out a little extra money to get something representative of that fender sound; however, with sweetwater upgrading these things with C Rex speakers, the amp presents itself as a cheaper contender against its $+ counterparts. Now I still think similar amps (in size) like the Princetons, sound better than the Blues Jr, but it's close enough that I choose to save my extra $ to invest in other parts of my rig like pedals and such. Overall this thing is awesome for being a budget friendly tube amp, so definitely give it a shot if you're considering it.
Rated 5/5

One of the best little amps around

I have owned my Blues Jr for 12 years.
It is plenty loud enough for a small club.
Sounds great at lower levels when practicing at home.
It will bother the neighbors if you want, but doesn't have to to sound great.
Great tube tone with any brand I have used.
Though I will say I do prefer the Sovtek tubes in her.
Nice over-driven sound with the volume up.
Nice clean sound with the volume down master up.
Fat switch boost is pleasant, not harsh. I have it on all the time.
Reverb is a spring unit,but a bit less than stellar.
That is simply a consequence of it's small size.
The reverb still sounds good if not great.

I do not hesitate to recommend this amp.

very nice

It's my first vacuum tube amplifier. After the first operation, I was surprised. I made more noise than expected and I was able to practice happily. I'm so happy.

It’s impossible to imagine a world without Fender guitars, and if you’re like many of the guitarists at Sweetwater, then Fender not only made the first guitar you ever bought " they made the last one too! From building the first mass-produced solidbody electric guitars and basses in the 1950s to creating some of the most influential amplifier designs in history, it’s no wonder why Fender is one of the biggest names in the business. As one of the world’s largest Fender dealers, we have countless guitars, basses, amps, effects pedals, and accessories in stock and ready to ship, whenever you need them. We’re always getting our hands on their latest creations, and there’s nothing we love more than to tell our customers all about them!
