Fractal Audio AMP models: Jr Blues (Fender Blues Junior)


* EDIT: Up-to-date information is available in Yek's Guide to the Fractal Audio Amplifier Models *

JR BLUES: based on Fender Blues Junior

Based on: Fender Blues Junior. This is a portable 15 watts amplifier, with dual EL84s, a solid state rectifier and a single input. It’s a different kind of Fender, not as clean. Some love' em, some hate 'em.

Fender (current model III):

"The Blues Junior is a 15-watt warm-toned, longtime favorite - the perfect grab-and-go tube amp for stage and studio. It is known for the fat mid tones characteristic of EL-84 output tubes, warm 12AX7 preamp tube overdrive, real spring reverb, simple control layout, footswitchable FAT boost and external speaker capability.”​


"The Blues Junior is a professional tube guitar amplifier introduced in 1995 by the Fender company. It is aimed at achieving the warm, tube-driven tone common in many styles of American blues and blues rock dating back to the 1950s, while remaining both portable and affordable. Fender frequently releases limited editions of the Blues Junior. All have the same electronic components and specifications but have cosmetic changes and often a different speaker, at varying prices. The Fender Blues Junior is most similar to the Fender Blues Deluxe, which adds a "drive" channel, an effects loop, and uses 6L6GC output tubes for 40 watts of rated output. The Fender Blues Junior was introduced after the Fender Pro Junior, but has entirely different circuitry other than EL84 output tubes rated at 15 watts."​

This amp is one of the few Fender amps with a Master control. Other controls: Gain, Bass, Middle, Treble, FAT push-button, Reverb. The Blues Jr. amp has a fixed presence circuit. No Bright switch.

We have models of this amp with and without the FAT switch engaged.
The FAT switch boosts gain and midrange frequencies in the preamp stage.

Use the FAT model and turn up Master to get the typical Blues Junior sound.


"Your new Fender Blues Junior is a professional tube amplifier with that classic, late night blues tone found nowhere else but in a Fender. Its compact size makes it ideal for rehearsal, backstage warm-up, and studio work. The control panel on the Blues Junior is located on the top side for easy access and the “chicken-head” knobs indicate all your settings at a glance. Volume, Treble, Bass, Middle, Master, “FAT,” and Reverb are all that’s needed to get every sound from “vintage clean” to “expressive growl” from this versatile amplifier. The Fender vintage Special Design 12” speaker is connected through a standard 1/4” jack allowing your choice of connecting to either the internal speaker or an external 8W speaker cabinet.
The “FAT” switch provides additional preamplifier boost adding warm, “Fender American Tube” distortion and may be controlled from the top panel or with the optional footswitch. The quality built into Fender amplifiers is the result of over 50 years of dedication and experience that our engineers and countless musicians have gained both in recording studios and performing on stages around the world."​

Use this model with no Damping (no Negative Feedback) to make it sound like an Egnater Rebel 20.

Cliff: "The Eggie is very similar to a Blues Jr. Basically the same preamp with some minor tweaks."​

The combo has a 1x12” Eminence Legend or Jensen (C12N or P12R) speaker. Cab #79 is an IR of this speaker.

Cab Packs 2 and 10 provide more Blues Junior IRs.​

Is there a way to tag other forum members in these threads, because I know a guy doing amazing things with model.


Had the opportunity
to play through one of these yesterday while checking out a Suhr Classic pro in store, very nice, now I'm investigating the Fat Model in our Axe and it holds up perfectly..

I love this model in the box - I like the actual amp as well, but in the axe, where you can easily hook it up to a 4x12 or squeeze every bit of juice out of a single speaker, it really sings. I like it at least as good as some of the more legendary Fender Models.
