I recall filling in for a blues band a few years back. At the first rehearsal, the drummer commented on my '85 Persuader saying, The sound of at that bass is incredible and it doesn't 'click and clack' like our regular bass player's Fender.
The guitar player laughed and told the drummer, It's not the bass that doesn't 'click and clack'.
I generally have a light touch and I still generate plenty of meat and/or earthquakes. It's all in learning to harness the power you have at your disposal in your amplification combined with the power that resides in your fingers..... I too like to let the bass know it's being played once in a while, when it's called for, but the bass also seems to know when it's being caressed and is capable of giving back beautiful tones and moans of pleasure.
But to the point of the original thread, I use my fingers almost exclusively. When covering a song that requires a plectrum, I'll usually use one. Oddly enough, I prefer the good ol' Fender mediums.
