I recently decided to give Brian Bromberg's middle finger popping technique a try. Even if it doesn't work out I will develop control & be better able to do various maneuvers such as the flaminco strut. For that reason I try to pop using the ring finger as well. The intrinsic problem with the middle finger is that it has less leverage, & there's less coordination (or dexterity) than the index finger, so it feels weak & awkward. But it's not really weak given how loud those pops are. So much so that I'm almost afraid to pop--but I'm working on getting greater control of popping technique by popping muted strings, while alternating fingers. One thing I've noticed is that the my Hi Beam G string's intrinsically louder than the d string when popping. I think that's because of its different construction with a single outer winding layer, there seems to be more high frequency output compared to the d strings output. So the result is that unconsciously, I've grown accustomed to actually popping the d string harder & the g string lighte with my index fingerr. My question is if what I'm describing's a common problem, & if it's rectified with compression. I don't have a compressor yet. Also, I took off the chrome neck pickup gaurd of my Marcus Miller bass, as it gets in the way. I recently have made it a point to always have my fingers poised to pop by keeping them curved with the knuckles resting on the pick gaurd. Now this results in my knuckles frequently banging the pick gaurd as I practice slapping. I don't mind thee sore knuckles, but is this indicative of poor technique?
