Hello everyone, I'm a newbie at bass and I understand the two finger (index & middle) technique. I understand having it very strict when alternating the fingers to play a fill or fast run. Is it so necessary that I must alternate the fingers when playing a slow or mid-tempo groove that has notes tie together? Also, I saw a video of someone saying resting your thumb on the pick up is bad because the acid from your sweat will ruin the pick up? is that bull 5h!t? Thank you for your time!
