I have to use a practice mute quite frequently because my wife frequently has meetings when I practice. I'm currently using an artino which has good sound reduction, but is pretty bulky. I saw wmutes practice mute is a clip on and has good reviews.
Anyone tried both and if so what do you prefer?
I use one, and I like it. It mutes as much as some practice mutes, though perhaps not quite as much as a solid metal one. Not cheap though.
I have had solid brass which I ditched very quickly, and I've had an Artino which I can't find any more, so I may have ditched it, but I'd be surprised. Otoh, it's a bugger to fix to your bridge and I'm not convinced it's guaranteed not to damage a violin. Also your view over the top of it is restricted.
Gordon, the OP was asking about a specific mute called "Wmute"
Wmutes is more of a metal clip with a cork lining. At least it won't be as bulky and give more space near the bridge for bowing.
WMutes does sell the heavy practice-type variety with the same clip-on design as their performance mute, but for a steep 65€. The reduced size of this mute aside, I can't imagine it being so much better than other (cheaper) practice mutes that the cost can be justified...
I ended up buying it. With a black Friday deal and a credit card bonus it brought the price down about $20. I'll see how it compares to the artino.
If you haven't tried a Wiessmeyer (Viowess) Catrpilr, you might want to. It's 3-D printed, quite light, and reasonably effective at cutting down resonance without destroying tone quality.
