Mute Clamp Concept

Yes, The hinge should be on the small string side. <

With dense foam it wouldn't seem like any vibrations would cross to the other strings. It shouldn't be that hard to quickly make a working prototype to prove wether it does or not.

I understand the reasoning here - seems logical. Initially, I did not consider the difference in pressure across the strings.

When I tested the foam sandwich it actually seemed like the smaller (tighter, more pressure) side might be better on the fatter strings, because they required more pressure on them to have the same dampening effect. This is kind of counterintuitive at first, but I think it's going to require some testing to find the best result.

Amazing feedback here - 20+ minds are better than 1!

Your concept is now very similar to the sound block used on upright basses.

It also reminds me of devices used on mandolins and jazz guitars to kill overtones, such as the Weber Wood Nymph

Yeah but do they still make that thing?

Of course.

Yes you are correct. That's the other thing to consider when figuring the shape of your dampening foam. That's why when you look at the foam mute installed in the ashtray of a vintage Fender, it's wider over the fat strings and narrows down over the G.

Had a random thought about the C clamp design, version 3.

It'd be cool if the closed end of the clamp had some provision for adjusting how hard the foam pads squeezed the strings, from above and below. That'd let the player choose how much damping effect it would have, and also adapt to different gauge strings. Like, I'm using a Circle K balanced tension set and the B string is a .142! Way different from one of the .120 sets, I figure.

Subd. And I never subscribe to threads.

I think you should continue pursuing this. Mutes that are currently available (the ones I found anyway) for electric basses mount to the body and a removable design is needed.

And remember, the guy who invented quick-release sockets and wratchets sold it for peanuts and was broke upon croaking. If someone steals your idea, we're all witnesses.:p

I'm not convinced that the mute needs to contact the body of the instrument to prevent overtones. For one, the foam will be in contact to dampen sympathetic overtones from other strings (kinda the whole point of the device) and secondly, if I palm mute with my plucking hand I don't get any sympathetic overtones, and my hand isn't attached to the body!

This is seriously cutting into my practice time.

Here is the simplest one yet. Seems like it could work... in theory. But now Im wondering if its a bad idea to cover the top of the string (as well as the bottom)

That is unbelievably cool looking. I think using lighter foam like your paper prototype might balance out the fact that you're using foam on top and bottom. I'm guessing the foam will need to be tapered somehow to offer the same amount of muting to the high strings and low strings, I'm not convinced the device would need to clamp at all. Adjusting the angle (how far from the bridge you attach it) will probably offer good control of tone. This is actually a really elegant solution that you could probably produce and sell at a really good price point.

I would love to try one, since I usually just palm mute, cuz I hate messing with random chunks of foam.

U-shaped clip as shown above.
Minimal thickness felt pad on the bottom in case it hits the instrument.
Minimal thickness felt pad where it contacts the bottom of the strings.
Thicker piece of foam where it contacts the top of the strings.
Thumbscrews on the top of the device to adjust the tightness with which it grips the strings.

I've never heard a foam mute that sounded as good as a human hand.
Experiment with different materials to find a best sound.

What program are you using to sketch those drawings?

Good idea, looks cool!

I think the prototype #2 would work best, anchoring against the body instead of #3's floating design. It might be hard to strike a balance between enough pressure to mute the strings, and ease to slip over the strings, with design #3. I haven't experiemented with that though!
 
#53
Subbed. I'd rather have something that I can quicly attach/remove without mounting it to the bass. The foam would have to be tapered somehow so that there's even pressure on all of the strings. They do need to ring out somewhat or it's just a thud - not the thump we're looking for.
 
#54
You could also make it fairly narrow. I would think that people would generally slide it up against the bridge saddles so it's out of the way.

The slip-on kind in your version 3 would slide on the E string first and have a precision taper. If the taper was correct then you could use denser foam.
