Ultimate GS-55 Genesis

Got this because of its size - needed something small to fit in my gear bag. And it is certainly very small! It's a bit tricky to remember to fold the arms together the correct way (not like you won't be able to fold it, but it takes a few extra second each time). It's an odd little stand, in that it doesn't seem like it would be able to hold a guitar comfortably, you'd almost think the instrument will tip over if you down put it down very carefully. But at least for my instrument it seems the rubbery upper part has enough friction to keep it upright without risk off tipping over. In the beginning I was a bit weary, but now I'm quite comfortable that it will hold my instrument in place.

I keep my 7 string bass guitar (Conklin GT-7) in this stand, so I guess you could say it fits all guitars/basses.
It's durable, portable and seems to be able to fit anything in there.

Never had an issue of a bass falling out of the stand, the bass moved a bit the other day, but I hadn't placed it into the stand properly. So if you do it properly, no worries.

The rubber of the legs holding the bass is coming a bit loose, but nothing a bit of gaffer or super glue can't fix. It's permittable after three years of (ab)use.

The ability to fold it up for travel is awesome.
Best stand I got so far.
Recommending this.

I have had this stand for a while now and have found it to be more than sufficient, given its price. It is not the most ergonomic of stands when folded up (the Millenium GS-2012 definitely wins that prize), but in all honesty it is seldom that a guitar stand like this is constantly being assembled / stowed away multiple times a day.

The stand is very sturdy in day-to-day use and its footprint is a touch on the large side if you are limited for space. Likewise the angle of incline could have been reduced a touch to help minimise space reduction in compact spaces.

The one major design quirk is Ultimate's decision to accommodate both acoustic and electric guitars on the one stand. Why not go the route of the K&M 17540 which is marketed just as an electric guitar stand? I say this because the over-extended arms on the stand end up being the perfect obstruction if you have placed your guitar down with its strap. The end results is often a guitar stand that has keeled over and numerous shouted expletives.

I'm pretty happy so far with this stand. I've used it for a large-body jazz guitar and a heavy solid-body electric and it's kept them up quite safely.
One thing to be careful about, if the strap of the guitar is on and trailing around the stand, when you reach for the guitar the strap can get tangled in the stand. If you're not careful this can cause you to drop the guitar or let it fall!
Also be careful no to let your guitar lean back at a wide angle, this is less stable.

I've had no problems with the stand affecting the finish of my guitars, the materials are soft and harmless.
