Gold Tone Ultimate Mute

Pros:
- Easy to put on/take off.
- Not in the way when playing.
- It increases sustain.
- Cheaper than the Deering one but with the exact same function.

Cons: It decreases the perceived volume a bit but not as much as I had hoped for (I estimate it to 25% or so). It mostly scoops out the mid register with lower and upper register still prominent. When digging in the sound becomes slightly distorted. It is not very pleasant sounding to my ears. Also the velcro sheds.
