Hi, my name is Jim Lee. When I first learned how to do the DoubleThump, it took me over 8 weeks… my video tutorial will show you how to do it in less than 8 minutes.
This bass guitar speed technique can be used with almost any style of playing: from chords to intricate bass lines. I like it because you can play 2x faster with less effort.
Here’s a sample of me playing using this technique.
There’s no risk because I offer a 100% money back guarantee.
