Bogner Atma Review – EL84 Powerhouse Tube Head!

Updated on by Ross McLeod | There may be affiliate links on this page.

The Bogner Atma is a highly powerful amp head with an all-tube design. It features several tone-shaping controls and is suitable for rehearsing, recording, and live performances in any setting.

The tube amp head market has become saturated in recent years, but the Atma stands out amongst the crowd. Let’s take a look at the standout qualities of this versatile Bogner device.

Bogner Atma – Overview

A common pitfall of all-tube amp heads is their tendency to be one-dimensional, but the Atma defies this stereotype. With three era-based compression presets, you can instantly tap into the tones of the ’60s, ’70s, and ’80s.

The energetic output of the Bogner Atma is largely resultant of its two EL80 power tubes. A classic choice in British-style tube amps throughout the years, these tubes provide a blend of warmth and grit.

Switchable power modes allow you to choose between 18 watts, 5 watts, and 1-watt operation, depending on the environment you’re playing in. These are just a small portion of the features included on the Bogner Atma.


  • 60’s, 70’s and 80’s compression gain presets
  • Three 12AX87 preamp tubes
  • Two EL84 power tubes
  • Roust hybrid wooden/aluminum housing


  • No onboard reverb

Build Quality

Tube amp heads need to be able to cope with the inevitable wear and tear that occurs when moving the device from the practice room to the studio or stage.

With a durable chassis made from a mixture of wood and aluminum, the Bogner Atma is built to withstand heavy usage.

The amp head is handmade in the USA, and all of the onboard rotary controls and switches are solidly built. There’s no danger of the Atma buckling under pressure, and you don’t need to worry about it being bumped or moved around during transit.


Bogner has installed a variety of features and controls on the Atma, all of which provide ultimate freedom over the tone and color it produces.

In addition to the three compressor presets, there are three channels – clean, crunch, and lead. Each channel engages the power tubes in varying intensities, which adds a little bit more heat to the signal.

Modern tube amplifiers are built upon the success of their predecessors, and the Atma certainly doesn’t overlook its heritage. The EZ81 tube rectifier allows you to instantly add a vintage touch to the amp head with the flick of a switch.

Additional Features

It’s fair to say the main selling point of the Atma is its powerful tube-driven tone. Nevertheless, the wide selection of additional features is what sets it apart from other similarly-priced devices.

There is a gain control, a three-way EQ for adjusting the prominence of the bass, mids, and treble frequencies, and a CR gain for injecting some crunch into the output.

A serial buffered effects loop is very useful if you enjoy using pedals. This allows you to isolate certain effects and ensure that they interact with the amp head in the cleanest way possible.


There’s no doubt that the Bogner Atma is one of the finest all-tube amp heads available. It’s bursting with customizable features, and the tone is exceptional.
