Cool, I use it more steadily like back beat on my notes. I am trying to do a thing like the Rock a Billy upright guys do.
I was kind of meaning more of how physically do you make your percussion on the bass?
I use two different ways depending on the style of the song. First one is for steady down beats and is just like upright slap, pluck downbeat note away from bass and ghost note back beat as my finger comes back down on the string sometimes I will accent the ghost more by clicking the pickup cover with my finger nail. Second one is similar to pick strumming ghost notes, except I use three of my fingers and don't rake all strings, just one at a time or pop the ghost gently if it is on that side of an up/down stroke. Getting a nice feel with the volume of each compared to played notes is challenging and fun.
