TaylorGirl, thank you for your detailed review. As I mentioned in a NGD post about my Taylor 562ce, I ordered this capo and you asked if I would share my opinion here.
The guitar store at which I purchased the 562ce provided two extra string sets plus a Schubb 12-string capo, so I had something to use immediately when I brought the guitar home. I use a Schubb for my 6-string guitars and that one works great. The 12 string version, though, provided the all-too-real issue of muting and creating buzz on some strings, so it took much effort to get it to work, and that was just barely. Subsequent to reading your review of the G7th capo, I placed an order.
In the meantime, I tried the 12-string pad that came with my Thalia capo, and it worked quite well actually. I am not a fan of the size, weight, and difficulty of placing the Thalia capo, but I may have stayed with it had I not already ordered the G7th.
My G7th Newport 12 string capo arrived two days ago, and it is hands down the best of the three capos I've tried. It is FAR easier to use than the Thalia and FAR FAR more effective than the Schubb. SO while the Thalia served its purpose, I will stick with the G7th for daily use.
