Mesa Boogie Transatlantic TA-15 Amp Head Review

We have recently seen the birth of some tube amp heads for electric guitars sporting a reduced size and weight, such as the Vox Night Train. This amp head format allows guitarists to enjoy their sound without breaking their back lugging gear to and fro. So now it is Mesa Boogie’s turn to launch its own portable version of a tube amp head, the Transatlantic. It’s up to us to test all of this and see if Mesa Boogie has succeeded …

Let’s Unpack

Mesa Boogie Transatlantic TA-15

First thing we notice out of the box, the very small size of the machine: 12 3/8”W x 6 3/4”D x 5 7/8”H, weighing only 12 pounds.

A “carry on” is provided with the head, just to remind us that this is a transportable amp head format. There are pockets everywhere for storing goodies found at the bottom of the box:

  • A footswitch with a button (Channel ½)
  • An HP cable long enough (about 5 meters)
  • A conventional AC power outlet

The head has a retractable iron handle iron gives it a “Lunchbox” look.  This is not the best example for ergonomics in action, but it deserves to be there (after 45 minutes in the crowded subway, my hands longed for a plastic handle). The Design and the buttons “gas cooker” style provide an unusual looking product, a bit out of time, vintage, but at the same time utilizing modern materials such lots of metals.   Finishes are well cared for and we don’t notice any defects, the “Made in USA” has its effect.

The highlight of the show is when the head is turned on: a blue light emanates from the bowels of the beast to dazzle the eyes.   Question of taste, I think it looks a little Jacky-tuning, but this sensation disappears when the sound comes out of the speaker.  We would have liked the option to disable the effect of “Neon 205 GTI”…oh well!   Let’s forget this episode in bad taste (which may be felt only by me) and move on to the bowels of the head.

The Mesa Boogie Transatlantic TA-15 is equipped with 4 preamp 12AX7 type tubes, and two EL84 type tubes for power amplification.  Patented technology provides three power modes for the amp section, selectable via switches on the front. In the 5 Watts mode, the head is working on a Class A tube power, 15 Watts mode, two tubes are used in Class A mode Push-Pull, while in 25 watts mode 2 tubes operate in Class A / B power .

Now let’s get to the settings …

Conclusion

It was a pleasure to test the Mesa Transatlantic amp head, once I passed the halo of blue neon light. We like the sound it delivers, rather vintage type, bluesy or rock, as one wishes.  However, we lament the lack of extreme sounds with gain galore for playing a proper palm mute. With all the little options that the amp front panel and independent channels offer, we come to find a pleasant sound very easily.  It can also be well used both during rehearsal, as well as in concert with 25 Watts and a footswitchable channel.  In short, if it did not cost the modest sum of about $900, the average guitarist would be in heaven and it would have been easier to swallow this pill.  Apart from that, the guitarists looking for a portable head with a distinctive sound, yet with many options, will be delighted!
