Bogner's stylish Atma guitar amplifier head is an all-tube powerhouse with tons of tones. The classy aluminum chassis and grille add unique looks to any rig. This 3-channel spitfire delivers chimey cleans to hard rockin' lead tones. 3-way voicing controls give the Atma focused tones from the '60s, '70s, and '80s. A pair of EL84 power tubes produces 18 watts of all-tube tone. Lower the volume of the Atma for rehearsal or studio gigs with the built-in power attenuator. Choose between 18 watts, 5 watts, or the bedroom-friendly 1 watt. Add a touch of class and a ton of tone to your rig with the Bogner Atma guitar amplifier head.

Bogner Atma All-tube Guitar Amplifier Head at a Glance:
  • A versatile tone machine
  • The man behind the amps
  • Handcrafted quality
A versatile tone machine

Don't let the 18-watt Bogner Atma guitar amp head's diminutive size fool you; this amp puts out huge sound. It starts off with three channels of tube-fired goodness: clean, crunch, and lead. These all sound great, but then you get to choose which era of amp you would like: '60s. '70s. or '80s. It's not just a quick EQ tweak, because these era selections change Atma's gain, voicing, and compression to produce the tones that defined each decade. The built-in power attenuator (18 watts, 5 watts, or 1 watt) lets you use this classy little amp at gigs, in the studio, or in your bedroom. Bogner's Atma amp delivers style and tonal versatility in a single package.

The man behind the amps

Though Reinhold Bogner began designing and building amplifiers long before leaving Germany for the U.S. in 1989, his career really took off soon after arriving in Los Angeles. He quickly gained the trust of many influential players including Steve Stevens, Dan Huff, Allan Holdsworth, Mike Landau, and Steve Vai, who all sought out his skill of modifying and custom building their amps. Eddie Van Halen entrusted Reinhold to overhaul and revitalize his number one Marshall Plexi, and the results were great. Soon after, Bogner Amplification was born, and the rest, they say, is history.

Handcrafted quality

Bogner amps and cabinets are handcrafted using only the finest components available. When you plug into a Bogner, you're not simply getting premium tone; you're getting the value of a piece of gear that's made to be played for years and built to handle the rigors of the road. From speakers to preamp and power amp designs, cabinets to cosmetic touches, Bogner amps and cabs are built to give you the best, most reliable playing experience. Period.

Outstanding

I've had the Atma for a couple weeks now and I can confidently say it's the best sounding amp I've ever played through. The amp itself is extremely versatile,the drive channel is fantastic in all modes however I've found my personal comfort zone in the tube rectified 70's mode. I have to say though that to me it's really a 2 channel amp with a boost on the dirt channel. That said that's pretty much exactly what I would set it up as if it did have 3 channels and how could they possibly fit 3 full channels on an amp that's just a hair over a foot wide ?
If I stopped there I'd tell you it's worth the $ but that's not all, it takes pedals extremely well AND ....I actually like the clean channel. For the most part I've found that most amps with dirt this good lack a little something on there clean channels. The Atma's 2 knob clean channel buy itself has a number of really good variations that can be easily dialed in and pedals sound fantastic through it, as well as through the very transparent effects loop.

Tough too.....

In addition to the other positive comments I'd add that this head is pretty tough. Mine fell a few feet to a hard floor and survived with any problems. I needed to reseat the tubes but everything works and sounds fine....
Rated 5/5

One of the most versatile amps available.

ATMA can do just about anything. Blackface Clean, Tweed Clean, JTM, JMP, JCM, through modern shred.

SS/Tube rectifier, 3 decade switch, saturation switch, plus a clean channel that can go from BF to Tweed and everywhere in between. IMO, the ultimate studio amp, and I can't think of a more versatile amp without going to a modeler.
Rated 5/5

Little Monster

Awesome little head. All 3 decades very useable. 70s is probably my overall favorite. Has the feel of a bigger amp, heavy so probably has a decent sized transformer. Loop sounds great. Been using with a v30 cube for about 6 months now with zero issues. Awesome.
