GewaGuitar support, Black (536525)

After trying this one and two others, one of which was the TENOR TPGS, I have to say this one has better ergonomics and stays on just as well. There's also less fiddling around with cheap suction cups. It seems like the more weight you put on it, the better it, er, sucks. This one might not fold up nicely in the case, if that's what you're looking for--but it stays on my guitar between sessions, without a problem.

Great portable design, but the suction cup is poorly made and weak.
