So I've been watching a lot of live performances, and I noticed most play with a double or single coil pickup. On my bass (the only one I've ever played I've been playing for 3 months) I have a single and a split pickup. I brace my thumb on the split and play. But after watching them I tried to play with my thumb on the single coil and it was very taut and sounded different. I decided to ask because I eventually want to buy a new bass that may have only a single or double pickup. Do bassists just play where it's really taut? Is my other split pickup affecting the sound?
