Thumb Fin Original – Bass Thumb Rest

Excellent tool if you wish to avoid drilling, changing placement, and or switching to a different scratch plate.
Import to EU and postage were eye watering - worth it but Yikees

I like that I didn’t have to drill holes or remove screws, heck all you to to do is set it in position and done. Bought the higher fin to give it a try think I’m going back for the set of three. It holds tight.

I thought this was a little pricey but really didn’t want to permanently install anything on either my mustang or my stingray so I opted to give this a shot. It works GREAT. It stays in place and does not slide or “migrate”. Really pleased with this.

Thumb Fin is a great add-on to my Gretsch Bass. It keeps my thumb off the E string and now my fingers do the plucking! Recommended by Danny Sapko

Love my fins! I got these for two U-bass. Makes playing a lot for fun and comfortable. Wonderful design. Acoustic-electric U-bass definitely needs the contact paper.

I messed up my order, and BJ was very kind to help me make adjustments right away. 🙏

Love this product. it makes you play bass so much better. I have the thumb fin on my Rickenbacker. ..........and you believe it I have 2 on my Stienberger.5 string.
both anchor so well no problems!

Love this product!! Looks great on my hofner and was definitely needed, improved my playing instantly. No lie 10/10 would recommend, makes a huge difference on a model like this.

Using on a Hofner 500/1. The pickup position doesn't leave a lot of room to rest the hand. The comfort and playability are much improved with the Thumb Fin. Would give this product a 4.5 if able. Will consider addition for other basses.

Maybe explore some optional colors - black, white, silver?

Danny Sapko sent me here! I'm so glad these exist. I don't want to permanently modify my guitar so these are amazing. I got another guitar with a pj pickups and using those pickups to place my thumb feels stressful. These Thumbfin's are a great option. Highly recommended. Thanks for this product!

I own a 15 year old Fender P bass with original single coil split pick ups. Pick up screws mounted on the edge where your thumb would normally rest. Placing my thumb on the pick would always bother me after playing a short while. The thumb Finn was an easy non evasive product which I placed on the pick guard & only took seconds to mount with the small suction cups that were attached to the Finn Thumb rest. Comfortable design, multiple colors to choose from & easty to remove to make adjustments. Over all I really like the product & only reason I gave it 4 stars was due to the price $20.00 each. But I would still purchase it again. Because of its ease to mount, comfortable to rest your thumb & that it won’t scratch or blemish your guitar.

I am using the new low profile version on my p-bass and I am loving it. The suction cups keep it mounted firmly in place. Great customer service. Highly recommended.

Feels so comfortable on my Fernandes BXB-55

Ordered one of these for my Fender Fullerton P-Bass Uke as I didn’t want to drill any holes into the small acoustic body. Found this gadget online and love the simplicity of it! (Only wish I’d thought of it myself). The yellow I ordered is a great colour with my bass’ sunburst finish, and I’ve had no issues with it moving so far whilst playing (albeit practicing and not gigging). Such a super easy way to add a useful function and a pop of colour. Thanks all!

This is so handy! As I have a SBMM sometimes the pickup thumbrest doesn’t feel comfortable depending on my wrist. So this is awesome to place it in tbe perfectly comfortable position.

At first look, I was not convinced. Two little suction cups, will they be stable enough? My first trial said no. I tried it on my Epiphone Violin Bass directly on the polyester finish. The suction cups moved and didn’t stick for a complete song. Then I used a little moisture on them and cleaned the surface before applying pressure. That was 3 days ago and it hasn’t budged! I get greater articulation and tone now, not to mention comfort. This is just the thing needed when you have a smooth clean surface to position it on and don’t want to drill or glue a thumb ramp.

I didn't want to do a permanent rest at the risk of damaging guitar and/or hurting potential for resale.
The thumb fin is aesthetically acceptable,comfortable to use, and leaves no permanent changes.

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!).

I used to make my own Thumb Rests from exotic wood 'pen blanks' for basses where it's tricky to find a place where to anchor your thumb, like Ibanez EHB's. The Thumb Fin is a fantastic solution. I actually removed the suction cups and used 3M double sided tape pads to attach the Thumb Fin to the top of the EMG pickup on my Steinberger (like) bass. This makes it 100% more comfortable to play.

I bought a new Schecter 5 string and it does not have a good place to rest the thumb. I also did not want to drill into my new bass to install a thumb rest I might not like. This was the perfect solution! The suction cups hold really well and doesn’t harm the finish. I can move it to wherever feels good that day. I have put one on my 4 string Gretsch now too! Shipping was fast and they included a gift with my purchase which was unexpected and nice. You won’t be disappointed!

The Thumb Fin is a gamechanger! I’ve gotten so used to playing basses with a thumb rest that playing without one felt so weird. When I came across Thumb Fin I knew it would be perfect for my Squier Rascal bass! It’s super easy to use, just stick it on and get playing!

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! 🇮🇹🎸

Fantastic

Very useful; I figured out where to place it on my bass ukulele by positioning the sticker first, and I love it. The only problem is that I paid €20 in shipping costs plus €22 in customs fees—a total of over €60! It’s too expensive. So, it doesn't make financial sense if you live in France.

I learned about thumb fin from seeing this great little invention being used on YouTube by a bass player who I follow - and had to get one.

I find no comfortable place to rest my thumb on either of my basses and thought this looked the ideal solution.

I had reached out to BJ regarding shipping to the UK which was quite expensive, I know he is trying to find a distributor in the UK - and really hope he does as the product is AWESOME.

I had considered retrofitting a screw on thumb rest to my guitars but couldn't find it in myself to drill holes in these beautiful instruments, and then I discovered you!

If you want to make your bass playing more comfortable then you need this!

Thank you BJ for everything and really hope to see you in the UK!
