Poor man's acoustic reflector!
For years I've been "evaluating" guitars by playing against a wall - probably 18" or so away is optimal for most guitars.
I was just sitting here watching golf and looked over at my laptop stand - and I realized it adjusts up and down and horizontally and vertically. When you get it adjusted just right, it reflects the sound directly back at your mellon  To my ear, it actually sounds better than against the wall (more natural with less 'boom'. I just spent an hour or so playing the Revival dread against it and it talked me right into keeping it for a while longer until we become fully 'acquainted"  This is the kind of stand I'm talking about - like 46 bucks at Amazon....

Good!
Cool reflection device….
And, I believe you may be GLAD you are hanging on to that Revival! Cheers Paul

Looking for something like this myself...
I'll be watching this post to see what others come up with. My own reflector is a 27" iMac screen, but I dream of even better passive amplification.
My own guitar and voice have never sounded better than a jam session under one of those modern city park picnic shelters. There was a metal peaked roof of hexagonal design that collected the sound and bounced it back down towards us substantially louder. Now I dream of some portable device like a folding fan that I could move around or hang on the wall or ceiling to get that effect again. Whenever I do a search for acoustic panels, I only get ones designed to absorb sound, not to reflect it.

That's a pretty interesting thing to me...now I want to optimize it. Looks like there are ratings for sound reflecting materials and frequency responses you can manipulate. Some interesting info under this link.

What would a rich man's acoustic reflector be? My solid music stand works well for me.

Sitting on the edge of the bathtub enclosure, facing inward, of course! Try it before you pass judgement...
When I was young I used to drive out to a nearby interstate rest stop that was all marble or granite. Playing a guitar in there sounded like the Taj Mahal. You did have to do it when there wasn't a lot of visitors, though. The crazy things we do as youngsters!

I would think those with woodworking skills could get very creative with this. I can think of some designs in my head that may work. Just don't have the time or the skills.

A few years back I channeled my 10 year old self to satisfy the old guy that occupies the current premises, and I bought this. It works really well!!

There is a small amount of reverberation with a bright top end, and I’ve noticed it can be eliminated with a small cloth taped to the metal. HE

I’m very interested in this subject. At home I have two places that sound extra good. One is in front of a curved hallway (yes we have a curve in our hallway) where the sound reflections surrounds me. Another is simply in an uncluttered hallway.
The music room is mostly wooden. When I removed the main carpet the sound dramatically improved. Long ago at school I’d play in a stairwell. Long reverb times! I’d like to develop a performance space that maximizes such reflections, so that acoustic players and a modest audience can enjoy pure acoustic music. I actually have the opportunity to create such a space in a year or so, if I can come up with a plan. I assume parabolic reflectors are ideal….I wonder if any are available commercially. I realize this is what many performance spaces did in the old days. I also realize there could be too much reflection, and for loud sounds one must have some absorption, but for acoustic guitar and voice I cannot really imagine that! Any further info is welcome. RFTinkerer’s article reference above was helpful regarding materials.
