Once pocket pickers start getting gigs then I'll pay attention?
If you have time to pick this up then you have time to pick up a bass?
Really, guys? That's a bit ridiculous.
This is a practicing tool, not an instrument.
I wouldn't walk by a drummer on a practice pad and say,
"Hey, if you can play on that, you can be playing on a kit..."
This could potentially be a great tool for practicing.
I, personally, do not take my bass to all of my classes
around campus (aside from my music courses), so there is plenty of
time I could spend using the pocket picker and not my bass.
I, also, do not pull out my bass whenever I am riding
along in someone's car. Again... time I could spend practicing my left hand.
There is much time that could be spent practicing that is not used
because of the inconvenience of a full sized bass.
Also, have you ever considered isolating your hands to practice
them individually? I often spend a lot of time developing my right
hand technique by simply muting the strings with my left hand...
Or I could be using this thing?
I have not used it, so I do not even know of its quality,
but just jumping at it and mocking it is pretty ridiculous,
especially if you have not even tried it.
