Very cool product, the shape is nice and comfortable, it effortlessly attaches, stays in place, and easily lifts off if you want to adjust position or remove (though I’ll keep it on my bass!).
Great little product! Easy to move around and make comfortable without drilling holes!
I have had a thumb rest taped on my jazz bass for a year not wanting to take the drill to it. This idea is really great, the material feels dense and solid and the shape is ergonomic and comfortable to play. Really great invention.
It is not possible to use the plungers to stick to a matte surface , so the company has a small piece of contact paper they provide that can allow you to stick your Thumb Fin to a matte surface. I trimmed the piece of contact paper so that it would look more attractive and there wouldn't be a bunch of contact paper sticking out around the sides. Worked well. I am very happy and I have these on three of my bass guitars
