The company’s new gig bag for on-the-go bassists covers well, everything

When it comes to carrying our instruments, we’ve usually had to choose between hard cases and gig bags. Nowadays, manufacturers offer a wide variety of soft and hard cases in every shape and size, with varying degrees of add-ons to help us bring the accessories every gigging performer needs.

With their latest bag, D’Addario seems to have taken all of this into account. The Backline Electric Bass Case, which measures 50.5″ tall, 15″ long, and 6.5″ wide, has a slick exterior made of water-resistant fabric, reinforced zippers that are easy to grab, and shock-absorbing padding to keep your bass in place throughout the turbulence of travel. The ergonomic straps are heavily padded without being too bulky, which is key for anyone who has to lug around a bass. The bag also features a cushioned back panel for comfort, which I quickly appreciated when I put this case to use.

Superior Exterior

The moment I unboxed the case, I noticed that it was well-built without being too heavy or boxy. The upper part of the case has two adjustable, locking straps to hold a bass or music stand in place. D’Addario even threw in a bottle opener next to the breakaway bag, the other noticeable exterior point of focus; it’s at the bottom of the case, held in place by auto-lock mechanisms that are easy to replace. The bag doubles as a slick backpack with padded and secured pockets for a laptop, tablet, MIDI controller, DI box, strings, keys, cell phone, or whatever other accessories one might need. The inside of the bag seemed spacious, which I immediately tested by filling it with three 20-foot cables, a Walrus Audio tuner, a set of strings, a cloth, and a notebook of charts, which all fit, with plenty of room to spare.

Interior Design

Besides its bottle opener and breakaway bag, the gig bag looks just like any bass case, but the interior is where it distinguishes itself. The shock-absorbing padding is generous, to say the least, and soft to the touch. With special material that lines the area for the headstock and bridge, the case guarantees that there will be no nicks and dings, and the body padding is thick enough to protect instruments from overzealous airport baggage handlers.

But the main attraction is D’Addario’s patent-pending climate-control neck cradle. At first glance, it might look like a well-thought-out way to keep the neck of your bass in place, but this cradle serves a far greater purpose: It holds D’Addario’s refillable Humidipak two-way humidity control packets, which ensure that your bass maintains optimal humidity levels—a welcome, very crucial element for anyone living in dry climates, as I do.

On The Go

Jaded by a recent experience with a too-tight gig bag that gave my bass a proper relic finish, I was immediately put to ease when I popped my Moollon J-Classic 5-string into the Backline’s spacious yet form-fitting interior. The neck rested firmly in the cradle, and the bass felt immensely secure. This bass is by no means light, but when I put the case on my back, I was surprised and pleasantly relieved.

When I arrived at my gig, I took a moment to appreciate the case’s oversized, easy-to-use zippers. I hadn’t even realized that it was something I’d notice. My bass was perfectly in place, with no new relic marks, and I was able to grab the cables and pedal without having to clumsily dig through the compartment. I was sold.

To truly test this case, however, I had to roll the dice on the safety of the breakaway bag. I decided to bring my laptop to a studio session, a risky proposition given the importance of my hard drive. But I figured that in the name of journalism, I should probably give it a shot. Sure enough, my 15″ MacBook made it there and back in perfect condition.

The Lowdown

I didn’t think I’d be this excited to write about a gig bag, but I have to say that I’m thoroughly enthused. D’Addario thought of everything when they created the Backline cases. I will be using this gig bag for a long time.
