"If you want to be melodic, don't slap." Tosin Abasi would like to have a word. Although, in fairness, Tosin's technique is more like thumping than slapping.
He is being Humble, The Dude is a legit bad ass on Bass and can slap and Thump like a Mo-fo. He taught me for 4 years, and I think everyone was blown away daily by his outstanding musicality.
