This valve kit fits all versions of the Fender Pro Junior. The amp is often described as the working musicians’ amplifier. It has been tried and tested for decades and is the kind of amp you will probably never sell. Yes, you mayt buy other amps that do different things but what the Pro Junior does, it does extremely well.

The latest version in the Pro Junior range is the Mark IV and this is what Fender say about it:

“Long-revered by players of all stripes. The 15-watt Pro Junior IV adds a modified volume circuit and a classic tweed appearance to this workhorse amplifier. A compact and straightforward tone machine, this amp is ideal for performing guitarists who need great tone and remarkably touch-sensitive dynamic response.

The Pro Junior IV includes a 10” Jensen® P10R speaker for a tight, well-balanced output with plenty of high-end sparkle.

The modified volume circuit breaks up more gradually. This allows precise gain adjustment to make tones that range from immaculately clean to devilishly mean. It also means tighter bass with improved definition when overdriven.

The stage-ready style features a lacquered tweed covering, vintage-style ‘50s grille cloth, chrome control panel with red jewel light
and a leather handle, giving it the unmistakable look and vibe of a classic Fender amp. Reliable, flexible and pedal-friendly, the Pro Junior IV is an ideal addition to any electric guitarist’s amp collection”.
