This is a side-by-side comparison of a J-Bass and a P-Bass. I play the same funk groove on both basses with different pickup settings too. The J-Bass is a Suhr and is an awesome bass. The P-Bass is a Lakland with Bare Knuckle Pickups which really work well on that bass.
There is a free PDF of the Funk groove, also with TAB. Follow the link in the video description on YouTube and I will email that to you. I’d love to hear what you think of the basses and whether you have a preference.
