I've been a footstool user since I first began studying classical guitar 12 years ago, but recently began thinking about using a support. I ordered the Murata mainly for the reason that it is not a suction cup support. The Gitano is a popular support, but I have seen the Gitano fail onstage on at least 2 occasions. If I had to pick a suction cup based support, I'd choose the Ergoplay because the suction cups adhere to both the upper and lower bouts that I find results in a more secure hold on the instrument. I chose the Murata because of how it clamps onto the guitar. I have read the various reports of the Murata leaving marks on the guitar, but decided to give it a shot. I got mine last week and my review is mixed. On the pro side, it does provide a secure hold on the instrument. It also swivels as the player moves back and forth. The cons are not big ones. First, the base that rests on your leg is brown. On the Strings by Mail website, the support is advertised as the "black" Murata, but it it's not completely black. Yes, it is only an aesthetic criticism, but if you're wearing black pants in a performance the brown might stand out. Second, when I first put it on, I noticed that it can be a little noisy as you move. I figure that you have to make sure that it's firmly fastened to the instrument to avoid any creaking sounds. Finally, my biggest problem with the support is one that cannot be shared by most players. My concert guitar is by the Italian maker Alessandro Marseglia. His design features a tapered body where the body is widest at the lower bout and gets narrower toward the upper bout. The result is a floating fingerboard that creates a little more vibrating surface as there is gap between the soundboard and the floating fretboard. It also makes the instrument unsuited to the Murata as the clamps are desingend for a traditional guitar, and as a result only 3 of the 4 clamps make contact with the guitar. That said, I am happy overall with the support as I can use it on the Takamine electric classical that I use on gigs and for teaching. I used it this past weekend for two gigs that I had and it was great. It allows me to sit for 2 straight hours at a time with no strain on my back. As far as my concert guitar is concerned, I may try an Ergoplay, but will probably continue with the footstool. But as far as gigs go, the Murata will be on every one of them with me.
