I’ve been using the Thumb Fin on my Fender Precision and I’m really impressed with it.
It stays firmly in place, feels very secure while playing, and it’s rare for it to come off. Even after several days attached, when it gets a little loose, a quick firm press is enough to make it solid again.
Most importantly, it’s genuinely comfortable and does exactly what I was looking for. You can tell that a lot of thought and work went into the design.
Great product, great idea, and definitely recommended for bass players looking for a stable and convenient thumb rest.
5 stars from Italy! 🇮🇹🎸
