I hate mechanical mutes. Palm muting is so much better.
I don't understand why people always say this. Yes palm muting is better depending on what you're playing because you can vary the amount of muting on each string. But if you're trying to play some Jamerson licks for example you can't do that with palm muting. There are times when you need to be able to use your fingers and apply a generous amount of attack but still have the mute, and you can't do that with palm muting.
