...let's be frank: the one supplied with Ibanez Q-whatever is shamefully not on par with the guitar's quality or price segment – besides, it wouldn't hold your new headless buy ever safe, not even on the way home from any physical music shop you may have bought it at [sidenote: why should you, then, considering Thomann's superior reliability, competence, and fairness in sales policy?].
although not exactly advertised for it, tipped by @only for the lulz review (thank you!), i just took the risk and ordered one – delivered ten minutes ago – for easy carry-around, carry-along of my Q52 whenever the hardcase's overkill.
fact one: size-wise, Mooer Wing Bag fits Ibanez Q52 like a glove – literally.
fact two: nose-wise, Mooer Wing Bag luckily doesn't stink at all – which isn't exactly the norm with guitar bags and cases, these days, unfortunately.
fact three: fabric, zippers, padding and lining materials seem of (borderline) decent quality for the current price – not wow, but not puah either.
fact four: you can't have this lie on its side and keep your guitar as such – maybe it works with the original instrument it was conceived for, but Ibby Q52 (whose body's made with a really thin and lightweight woodplank) always inexorably falls on its face.
fact five: shoulder straps only allow for backpack-like wearing, no shoulder-bag-like – and while unfortunately quite common, these days, this prevents you from wearing your favourite gear backpack when you intend to take your guitar in this bag to a rehearsal or gig.
fact six: while shoulder straps seem to do their job (shape- and fabric-wise), their final sliding belts and clips are indeed below poverty threshold in quality – and, considering how straps aren't designed to be user-replaceable, it's these straps that will most probably sanction the gigbag's end-of-life (though hopefully as late as possible).
mind the step, please: there's nothing wrong with this gigbag, as it happens to be the only option available for Q-Series headless guitars, therefore the one to go for – i would have personally preferred to spend some extra twenty bucks to get its quality right, or twenty less to reflect its overall value correctly.
