Special Offer

The Fender Blues Junior upgrade kit fitted with a Harma Bright Sapphire speaker and Harma valves will provide the classic vintage Fender crunchy open top sound with a tight British style low end. It is designed for the guitarist who demands top quality clean sound with the ability to provide a warm harmonic crunch.

The Harma STR ECC83 is used as it has the most neutral and clear vintage tone of all the current production ECC83/12AX7 types. The valves mid-range is very transparent and
very well balanced with nice even bass which has plenty of depth.

The treble has nice chime and is indeed the closest in sound to the Original G.E 12AX7 which most people consider the best 12AX7 in Fender amplifiers. We use a selected version to ensure that classic Fender sparkle.

The Harma EL84/E84L is chosen as it has the best clean sound out of any modern EL84. This is the special burst tested version of the E84L that is tested on the rig built for Brian May for the ultimate reliability.

In clean mode the valve has a well-balanced sound with a deep solid bass. The valve breaks up later than many others and in overdriven conditions results in a clearly defined creamy distortion. These characteristics make this the ideal valve in Fender amplifiers.

The problem that many players encounter when using a modern American voiced ceramic speaker in their Fender is that they can sound overly bright and harsh. The upper frequencies are very peaky and are too cutting especially when more gain is added .This results in a harsh almost brittle top which is not pleasing to listen too. A further issue with the Fender Blues Junior is that the standard speaker is very flabby and ill-defined in the bass response. This results in the loss of individual note separation and clarity.

The Harma G12 Bright Sapphire is a punchy American voiced speaker that combines the crunchy open top end clarity of an Original 1960's Jensen with a tighter British Style low end. The midrange has been designed to provide a warm smooth clean sound more even breakup when compared to the main competition. It is in the upper mids and top end response that set this speaker apart from all the others as top end is fantastically open with plenty of detail and aggression on solo's. The result is speaker that will make your Fender amplifier have enough clarity for you chords to sparkle and the right amount of fat crunchy sustain to make you lead sound sing with vintage harmonic warmth.

Here is what Jim McLachlan said after fitting The Harma Bright Sapphire in his Fender Deluxe Reverb.

Hi Derek,
Just a note to say how pleased I am with the new Harma Bright Sapphire speaker. I have fitted it to my Fender Deluxe Reverb, which came with a Jensen C12K originally, which is a nice speaker, but the Bright Sapphire beats it hands down. I am amazed at the difference it has made, Beautiful clarity and warmth at the same time. Nice tight bottom end and well defined mids. Top end is super clear but never harsh. I love Webers but this is every bit as good if not better. Truly a great speaker!! Many thanks,”

Jim McLachlan
