I think someone posted a thread about this last year, already.

I have a Third-hand Capo, which is basically the grandfather of this. I originally bought it after viewing Antoine Dufour's Memory of the Future video, which I was intent on learning. I've had it for quite a while now and have made a few tabs that use it, but I have not posted them on this site. I planned on writing up a little review and guide on how to read tabs using a third-hand style capo.

These two capos are basically the same. Both can emulate open tunings and can be clamped/unclamped mid-song. It is important to note that when using these for open tuning emulation, they only emulate some of the chord formations of the tuning they are mimicking.

I have to say that this one looks to be a bit easier to clamp/unclamp mid-song. I usually have to grease up my capo somehow to be able to move it effortlessly... otherwise there can be a bit of friction, and while still easy to turn it does not move as smoothly. On the flip side, it doesn't look as stable and I have heard similar comments regarding that from owners of the capo.

I searched before post this topic inside our forum but didnt find something about spidercapo, it why i create a new one.

On Youtube, after saw people recordings, it seems spidercapo works very well

According u said Natenm, this kind of tool works so it's a gret new for me coz I 'm always lazy to detune my guitar, so this spidercapo will save me : a lot of good tab are D-tuning , I tried to rearrange to Std-Tuning but generally it desn't sounds as good as original.

Well I m gonna probably buy it, Thanks for infos
