So having played for many years since the mid 70s and now after a hiatus from bass, I have been actively playing again. it's always been my first 'love'. I mention this because lately I have noticed that when playing in bands the notes from my bass are not all even in volume as if either the pickups are hotter on certain strings than others - they are set evenly in height in relation to each string. Consider the fact that my finger technique has perhaps waned somewhat over the years. I wonder if throwing in a compressor limiter, like a DBX 163X, would cure the variants? In addition when I play at lower volumes I can play faster and more intricate lines as opposed to when in rehearsals where louder volumes are needed and I am applying slightly stronger technique but also find myself getting sloppy sometimes due to this. Styles being played range from covers of 60s 70s. And much to my dismay a few originals (we need to do more ) yet I write much on my own as well. I have seen many bassists play with seemingly effortless right hand technique and wonder if it is a matter of more practice practice practice again.
