Muting technique - Why didn't I think of this?

[Bassfingers]

Hello, 

 

I was checking out a few p bass pickup reviews today and came across this guy. 

 

 

I've never seen a muting technique like this before - I wondered if any of you utilise this "thumb under the strings" technique? 

 

It looks odd but I would imagine it is pretty effective at killing unwanted noise. 

 

Where's my bass - I'm going to give it a go!

Looks weird, but if you have the clearance under the strings, why not?

Is a weird technique but a much better video than most pickup comparisons, helped me choose the SPB-2
