About the Fender Blues Junior:

This is probably one of the most popular amps in use and has been for many years.

This handy-sized Fender is a 15-watt warm-toned, longtime favourite, the perfect grab-and-go valve amplifier for stage and studio. It’s known for the fat mid-tone characteristics of the EL-84 output tubes and warm 12AX7 pre-amp tube overdrive.

In addition, there’s a real spring reverb, simple control layout, and external speaker capability. This is a loud amplifier for its size and is a clear favourite. The Blues Junior can also be modified with some quite cool mods.

Finally, this is a handy little amp for all occasions. You can pick it up with just one hand and it will fit in the smallest boot. Yet you still get all the power and tone of a classic valve amp.

So if your budget is tight and the places you play are small, this is a great choice of amp.

 Trustindex verifies that the original source of the review is Google. I recently purchased a replacement tube set for my Line 6 DT25 Head amp from Ampvalves.
The website is very user-friendly and makes it easy to find the perfect tube set for your amp.

Due to an error by the parcel service, my shipment did not find its way to me. After contacting the support, I was helped immediately and competently.

The quality of service was truly exceptional and exceeded my expectations. A special thanks to Barry Tyler. Hey Barry, you did a very good job.

The tube set arrived afterwards in excellent condition, exactly as described on the website.

The quality is remarkable. It’s well worth the money for their high-quality tubes. I highly recommend the tubes from Ampvalves.
Also, my amp gives grateful feedback with a wonderful fresh sound.
