Bad technique or equipment?

[dotz]

David i was watching your video of you playing.

I wanted to ask you a question on technique, i have spent the last few weeks trying to adjust/re adjust my right hand picking palm, so i can mute my strings i am not playing because so many strings are ringing out. i wonder if you have ever had this problem and how you over came it, it is extremely fustrating for me right now.

do i need a compressor or noisegate? could they help? or is my action too low? over the internet all i can seem to find is 'use your palm' but it is not very detailed at all.

thanks in advance,

damien.
