Thomann Voyager Producer Bag

You have room for a lot of different gear in here.
Lots of pockets and spaces to keep stuff organized, but some of them could use a latch or strap to keep stuff from falling out.
I would keep this in mind when putting little stuff in the pockets, or expect to find them at the bottom of the bag later if used as backpack.

I would say this is more suitable for carrying shorter distances, even if it converts to backpack. The bag itself also weighs a bit.
It's great to have the option, but if you have to walk around a lot with gear where the weight adds up, I would probably rather invest in something that is primarily designed as a backpack.

But then you will probably be paying quite a bit more.
Overall I think this is quite good for the price.

I was looking for a cable and module bag for my Roland TD-27. And after a very long and thorough search and reading reviews, I chose this bag, and I was not mistaken.
The quality of the bag is great and it holds the TD-27 module and many cables and other small items. This bag has pretty dense material and has 2 large pockets inside and one of those pockets has 3 sections. The outer pocket is big enough to put little things in there. I am always satisfied with the quality of Thomann products and this time I am just as satisfied.
Before I put the electronic drums module, I highly recommend buying a cover for the module to avoid scratches, during transportation and possible bumps.
Since there are no special covers for the Roland TD-27 module in this store, I bought this Thomann Mixer Stretch Dustcover at random and it fit my module almost perfectly. This cover will also fit all modules, including the TD-50 and others. It's really big!
Peace and success to all fellow musicians!
