Briefcase Gig Bag

Choose your model from our List of Thousands for prices
Custom-Made to Fit Your Gear – send us your dimensions.

The Briefcase Gig bag can be made most any shape. What distinguishes it as being different from the Clamshell Gig Bag is that it’s made with webbing handles, rather than handle openings. The webbing handles are on either side of the zipper and a fabric grip is sewn onto the handle which wraps around the 2 handles and Velcro’s closed.

This soft-sided bag is made with tough 1000 Denier Nylon Canvas (Cordura) on the outside and thick quilted padding on the inside to cushion and protect your gear. It's perfect for:
  • pedal boards
  • mixing consoles
  • lighting controllers
  • keyboards
  • computer equipment
  • recording equipment
  • Amps
  • Speakers
  • And anything else you can think of
We use heavy duty, top quality zippers that glide open and closed. You can add a shoulder strap with a shoulder pad, and for heavier bags, a cushioned handle grip. And of course, you can add a pocket to the outside of your bag.

Custom made in the USA.
*Please note: We will send dimensions to you when we receive your order so you can double check that the correct model was ordered and that the dimensions we have match your model.

Today the cover finally arrived! It fits snugly. I do especially like the way the handle area is covered with the small part of fabric going underneath the handle. :D So thanks for the great service!

Thank you for your service. I received everything well before Christmas. The Seymour Duncan amp cover is a perfect fit. You even got the slight incline on the top 5 inches just right. The pedal board covers fit a little loosely, but that's the way I wanted it. My husband was very pleased with this gift. Thanks again for all your help. Let me know if I can leave any feedback on your website. Thanks for the excellent quality as well.

Wow Susan! These cases are really great... you did it again. My wife was just laughing at me... "it's funny the things you get excited about," she said. But looking at my amp and cab in your perfect cases, how could I not be excited?

I received both the slip and clamshell covers for Davis' (my son's) Carr Rambler and they fit perfectly as you and I knew they would! Just wanted to send a big thank you to you and your staff for making these exquisite covers for my son. His cherished amplifier will now be protected the way it should be. I, also, thank Steve Carr for recommending Studio Slips to his customers.

I received your amp cover for my Matchless DC-30. I used the cover last weekend going for the jam with my mates in the studio. I am very glad that I order this beautiful amp cover and I will value it for long time. Just wanted to say thank you and I planning to order another cover for my modified Fender Super Champ one day.

I have the best dressed gear anywhere thanks to the perfect fit and fair price of Studio Slips. Proprietor Susan B. is the best at her craft and always goes the extra mile to ensure a customer smile. I'm about to order very hard-to-find covers for a pair of Tapco 6925 speaker columns. I'm impressed that SS already has the measurements in their data base, so all have to do is order. I'm now in the Austin, Texas area, so my gear gets much more use. But, it never ages thanks to the quality and form fit of Studio Slips. As long as I can hold a guitar and sing a note, my stuff will never see a naked day with Studio Slips. Fred M., Deep in the Heart of Texas

I meant to send this email earlier? my speaker cover fits perfectly, I?m extremely happy with it, and I?ll recommend you all my musician friends. Thank you.

Wanted to let you know how much I like the amp cover. This cover offers all the protection I need and the exterior isn't showing any signs of wear. We play about 7 to 8 shows a month - club dates to concerts and just about everything in-between. This cover holds up and makes it so much easier to transport my amp. So bottom line is I'm more than satisfied with my Studio Slip. Heavy touring where equipment is getting a lot of abuse can justify road cases but for everything else, I think this is the way to go. The quality, workmanship and attention to detail is top notch. I will order again as soon as the need arises. Thanks!

~Steve, Waxahachie, TX

Received today, and PERFECT! Really a nice job. Easy on and off, just the right amount of "extra", and the back handle opening was right on. Thanks for the work, and you'll be highly recommended. Will be ordering from you again, no doubt.
