I went on a tear looking for a good gig bag last year, and wound up using my hard cases. Every one of the current ones on the market seemed to have drawbacks.
I was initially impressed with the Mono bag, but noticed that it has a very abrasive-feeling piece of fabric just over where the bridge of the guitar would be. That’s fine for the metal parts, I guess, but some edges would have been against the wood, and seem like they’d put swirl marks, etc., on the finish of the wood. So that was out. Granted, I’m fussy, but the bags were for PS guitars.
Next I looked at the Reunion Blues Continental - protective bag, yes, nicely done, except why the nylon diamond pattern interior stitching that’s both unnecessary, and because it’s nylon thread, kinda likely to eventually swirl up the guitar finish? Regular furry stuff without the stitching would be preferable.
I had two of the old Reunion Blues leather bags before the new management came in; they were sturdy, had soft flannel liners, and were just great, but they aren’t making them any more. I’d previously sold mine with some guitars, and was SOL there.
Access is importing a nice looking leather gig bag from Germany, but I haven’t seen one in person, so haven’t bought it. The bag does look nicely made, and leather is stiff enough and thick enough to offer good stiffness and protection along with the interior padding. So it’s worth looking at. I think they have some nylon ones, too. Not sure, you might want to check.
InCase used to make a fantastic gig bag, including the original one for the John Mayer Strat model; it fits a DC PRS, and if you can find one, I recommend it, because I had one for a short time (sold the bag with the guitar that was in it, dumb move). It may have been the perfect gig bag. InCase no longer makes it.
The Gator bags that 11Top is recommending do look sturdy and protective. So I went to buy one, but two of the brand new ones that I looked at the day they came in to my local store had the plastic liner poking out from the stitching; the bags had literally fallen apart in shipping. Not a good sign, I thought.
If I go to experience I want to take a look at the PRS gig bag.
It’s REALLY hard to find a great gig bag these days!
Oh yeah...final note: The much-maligned SKB cases that come with some lesser guitars are actually very light, protective, and last for years and years. Might be worth considering (I’m not referring to the heavy duty road cases, just the standard stuff).
