Gravity Vari-G 9

I hesitated a lot before buying this stand because I was afraid my Gibson Firebird and B.C. Rich Mockingbird wouldn't stay in place, but they do!
Another big pro: just by using the neck holder you can hang your mandolin, ukulele or shorter scale instrument as if it was a wall mounted holder, which is super handy for me; the neck holder is firmly locked by the clip-on design, but I wouldn't hang anything too heavy: that's not what it was designed to do after all ;)

Though I'm very happy with the product, I think it has a few drawbacks you should be aware of:
1-it's not ideal for guitars with nitro-finish (I have two of them) so you better put some sort of protectuve cloth between the stand and the guitar. I wonder if there's any way of improving this with some particular material.
2-there's no "safety block" on the neck holder, which can be great because you can quickly swap guitars, but if you have clumsy kid or pet (or partner!) that might be a bit risky.

None of these were deal breakers for me, but it might be for you, I hope this helps!

The Gravity GSMG09 VARI-G 9 Guitar Rack For 9 Instruments is the perfect storage solution for electric, acoustic, and bass guitars. This Gravity guitar rack is crafted using heavy-duty steel tubing with a rugged black powder-coated finish. The rack features a selection of soft-touch yokes, which provide excellent protection and stability for the neck of your instrument. The VARI-G's yokes are detachable, allowing you to position your guitars to fit your needs, or create more horizontal space for guitars with deeper bodies. Special care has been taken throughout the design of the VARI-G 9 to prevent scratching to the guitars it will hold, the interior edges of the yokes and sides of the frame are coated in a soft touch rubber and the body support rails are coated with a specially-formulated foam. The Gravity Guitar Rack is quick to set up, and can be easily folded flat for easy transport or storage when empty. You can also hang cables and straps on it.

Sturdy, easy to put together and not too expensive.

The best thing about this stand compared to other types is that you can clip the neck guides wherever you need them. I have a variety of guitar types and sizes so this stand allows me to put what I want exactly where I want: acoustics, electrics, non-standard shapes, etc.

You can space them out a bit if you need to. The vertical poles are the same diameter as the horizontal struts so you can clip any extra holders there if you like. I use the 2 I had left over as headphone holders. Very well thought-out piece of kit.

Pretty easy to assemble, and comes with a screwdriver on the off chance you don't already have one.

How many guitars you can fit on it will depend on whether they are acoustic or electric. I'm sure if you only have electrics, you can fit more than the 9 on the stand. In my case, I've got 3 acoustics/semi-acoustics that take up a lot more width than the electrics. I can still fit 9 guitars on the stand, with the remaining 6 being electric guitars and basses. I don't think you'll manage to squeeze 9 acoustics in though, but can't be sure.

I have a couple of Gravity products and they all seem well made, and I'd buy their products again without hesitation.
