I was researching wah wah mutes for a while. Heard good things about the Jo-Ral mutes but that they can be heavy. Watched some video reviews online of the Best Brass wah-wahs and decided to order the copper "cool jazz" model. I could not be happier!
This mute sounds awesome; very well made, nice and dark, SUPER free blowing (including the low register), and is pretty light-weight!
NOTE: The copper does gradually become darker once its exposed to air, but in my opinion, it looks even cooler then!
I highly recommend this mute!
