Stick around as I go through what makes this combo tube amp a must-buy for 2021

EL84 Provide That 60s Vibe

The use of emulators, mods, and other technologies was known as the “British invasion”. This sound was a cultural phenomenon. In the late 60s, EL84 tubes were one of the main reasons to get that tone.

The right amp uses a 5 tube setup with 2 EL84 tubes partnering with 3 12ax7/ECC83 tubes in charge of the preamp and reverb sections.

The very best manufacturers of the EL84 tubes were the ones that made the most money. It offers the full output from a small speaker. This makes it easily overdriven and in this process, it gives you that iconic sound we all associate with the 80s. You can already picture that treble chime in your head as if you were a part of that massive Woodstock concert.
Monoprice 15 Watt Tube Amp with Reverb Tone Demo and Review

The majority of ‘British invasion’ bands preferred amps that used EL84 tubes manufactured by the Mullard brand. At the time, the Mullard brand was known to manufacture the best EL84 tubes on the market.

The reason why this British sound resonated with the Americans so well was down to their uniqueness. The 6L6 tubes were popular in American music at the time and the new EL84 was a breath of fresh air.

Control Like No Other

These tubes will carry your tone.

For your control knobs, you have gain, volume, tone, bass, middle, treble, and reverb knobs. All this provides fines tuning for finding your right sound.

The tone control is more like a presence control so you tweak it based on your instruments. If you are playing single coils or humbuckers, you can tweak the tone and it will shift your EQ or equalization on the amp. Once you are certain they are doing the job, you want to have the ability to tune your tone to how you want it to sound.

The spring reverb does this process so well. It adds the reverb to the tone. It passes the tone along with the spring which allows the vibrations along the spring to create sound waves. This travels to the end of the spring and some of these leftover vibrations are amplified creating that echo sound we so familiar with.

This feature is only offered thanks to the 611815 Stage Right amp. You can turn this feature off/on using a pedal. Many guitarists prefer to have an on/off switch rather than a pedal.

The Design To Please The Masses

Everyone loves the classics. This takes you back to the 50s and 60s with the retro cream-colored synthetic exterior. The chrome corner guards are a fitting look for a durable design. There is a leather handle making it comfortable and easy to pick up. The cloth speaker grills add a tough touch.


The Monoprice 15-watt tube amp sports many pros for what is needed in your guitar amp.

Responsive Tube Amplifier

There are 3 high-quality 12AX7 that push the reverb and preamp part enabling a more distinct sound. The EL84 delivers that punch and that distinct ‘British Invasion’ sound we all love.

Inserting Effects Between Power Amp And Preamp Gives Versatility

With the fx send and receive options, you are able to fine-tune these settings to your liking. The amount of different sounds you are able to replicate with this setting alone makes it a must-have.

Switch between full power and 1-watt limited amplification

We all have that one neighbor that complains about the noise you are making. There is a 1-watt limited function where you are able to practice late at night or at a lower tone unlike the Joyo Bantamp Zombie which doesn’t do well on lower volumes. This is such a convenient design for guitarists who love jamming at home. The 15-watt packs a great punch if you are looking to blow the roof off a place during a gig.

Many compare the sound loudness to a Double Stack.

The Design Looks Sleek

Textured synthetic leather looks the way you’d expect the retro amp to look. It has the 50s and 60s retro shade of cream that will fit into any setting. The amps cabinet has a nice open back and a cloth speaker grill which protects your device if it falls over or not.

Durable and Versatile

The corners of the device have chrome guards that are excellent for durability. The leather handles make it easier to carry around.


Any top-tier product has minor downfalls.

Spring Reverb Only Works Via A Pedal

It would be better if the spring reverb came with a switch to make it accessible. The majority of the time you don’t want to focus on the foot pedal when you are playing and rocking out.

What Customers Think Of The Amp

There are over 850 reviews on the official Monoprice website, and customers cannot stop raving about this product. It has an average rating of 4.7/5 which makes it an overwhelming client favorite.

The customer service received is also a notable function of the overall experience of buying the product. Shipping times are fast and reliable and the amp is packed in a box that is in another box. How much more safe can one be?

Your amp or electronics, in general, won’t get damaged. The customer says the pictures don’t do the look of the amp justice. In person, it looks stunning to the eye.

People loved the 1-watt function and said it performed better than they could have ever expected. This feature makes it an excellent practicing amp alone.

Monoprice 15 Watt Tube Amp Review – Overall Impression

You can’t go wrong with purchasing this amp. It is a no-brainer if you look for a high-quality amp that provides that old-school feel and sound to your collection.

The design and sound layout of the Laney CUB-12R are similar and some may even say Monoprice outright copied them. For us, this is perfect because if you were to buy a new Laney Cub 12R, it would set you back $581. The value of this design and sound quality alone stacks up to those much higher in their price range. The Monoprice website offers its design for $249.99

The look and feel of it give you a retro 50/60s vibe and overall you will love it. The EL84 is the standout feature when it comes to that punchy sound we all crave. Kitted with your choice of hair raising 15-watt sound or a more mellow 1-watt setting. This makes it a versatile amp for many scenarios.
