Don't be like me, I didn't read the website correctly. I have an ash bodied bass, and the Thumb Fin wouldn't adhere to the body. Thumb Fin sent to me some contact paper and the Thumb Fin now works a dream. My friend who is a professional bass player was also super impressed.
Therefore if you have an ash/wood bodied bass order contact paper when you order you Thumb Fin.
The thumb fin has an attractive appearance, and in principal looked like it should have worked: but unfortunately the sucked do not adhere to my varnished ash solid body bass ukulele. I think that the would be perfect for a more traditional gloss finished bass.
Great product! It took a few days for me to figure out exactly where I like it positioned. It would be nice if it were a little thinner, but I bet it has to be that size in order to have big enough plungers that will stick. One recommendation: clean the pickgaurd around were you want it with alcohol first. Also make sure the plungers are clean—but don’t use alcohol on those, just soap and water.
I guess I really didn’t have high expectations for this but it is a great product. I have used No-Mod in the past for other basses, but I needed a rest for a lesser known bass. This works great, very sturdy and lets me put a rest exactly where I want it. Highly recommend this!
