I bought this stand because in my tiny rehearsal we had to optimize space while promoting the sound quality, which is sometimes antagonistic.
In short my guitar combo was placed on the floor, and as I play very close to it I had trouble hearing me, treble (more directional than bass) getting lost in the room.
With this stand I could raise my amp while directing the HP in my direction and those of other musicians, I mean so much better, now I pick up all frequencies from my amp again.
 I use this stand for nearly 3 years now, it works very well tojours, I did a lot of scenes, it allows me to put up with me if you have not returned, ditto if it is transplanted it is more convenient.
The only downside is if moderately stable ground (like rotten scene made with pallets, Lyon will understand) it increases the instability of the building.
That said this is not necessarily due to the stand but the ruthless slois of elementary physics.
In short a purchase I regret it, he has already knocked a lot, it takes no place in a car or truck and it often helps out.
I go up the bill for all services rendered
The amp is about 70 cm from the ground and we can direct more or less upward.
I had to change my EQ, and I play a little softer.
However the use of a stand of this type reduces the low frequencies, we must push them a little.
Please note this stand is suitable for small combos, mine (in a ULTRA 112 peavey, equivalent in size to a villain 112 in a little heavier) I think is the limit of what we can ask it, so forget the larger amps with 2 HP.
It is a good inexpensive solution (45 euros when I bought it at Thomann, it dropped to 29 euros) and transportable to hear a little better, the machine looks sturdy and reliable, I do not regret my purchase, he gives me a familiar tool for my amp.
