Lots of things swirling in my head about this. My recent experiments with Evah Weichs on my ply bass have shook me from my steadfast committment to higher tension strings. It's clear to me that bass has great tone with those lighter strings, both acoustic and amplified. I didn't have quite the same experience with Spiro Weich or Solo at orchestra pitch on that bass so the string has something to do with it. Nevertheless I have noticed some value to lower tension strings I hadn't considered or discovered even in my experiments with Guts, the lightest tensions I've messed with. However it also seems that the lower tension strings with the darker core are a tad slower than spiro weich or mittels....at least for me pizz. Unless you are playing with a bow where the lower tension strings start easier and seem to require less bow finesse or pressure. I notice that the ply bass has a much thinner and lighter top than my carved bass so under any string it responds quicker but also dies quicker than my thicker and heavier top carved bass. Lighter strings seem to drive the lighter top better than heavier ones. I don't think that's the case on the carved bass. The heavier strings bring out more guts and volume on the carved bass than is possible on the ply bass. Anybody wanna chime in on this? I'm not sure what I'm looking for here. I'd like to hear others thoughts and opinions about string tension high and low and it's relation to tone, volume, usability, amplification etc.
