So I bought this for my GT-100 and I can honestly say I'm happy I did. For the price you get a very very good bag for your pedal!
Pros:
-Very well built, good material that will last you for quite a while.
-Very nice feel to the handle, doesn't hurt your hand when your carry your processor. It's really comfy!
-It's a perfect fit for my processor. It doesn't wobble inside or anything.
-Spacious front pocket, really large. I have the power supply for the unit, 3 6'meter long cables and you could fit some more stuff in there like an extra pedal or two if you use any.
-Zippers are well made.
Cons:
The only con I would say, as I read other reviewers mentioned as well is the fact that the shoulder strap is kinda short, would be nice if it was longer. I however don't carry it on my shoulder, as I generally have my guitar there, so that does not bother me.
Overall:
10/10 Great deal for the money! Really good bag for your effects processor. Plenty of space for cables and so on. Built to last. Looks awesome with the GT-100!
Cheers!
