Huge respect to everyone here, I have been lurking for ages and owe all of you a great deal. I am working on rabbath stuff playing 95% arco on my check ply bass with spirocore mittels. For ages i was using cheap rosin (not sure what kind), got myself some carlsson and things are going great. I am thinking of changing to corelli 370f, am I right in thinking i will get a darker tone than with the mittels? I'm also worried about losing volume, I love the projection im getting and though i don't pizz much lately, it's nice to know ive got the volume and growl there. I play with quite a low string height. Are there any other strings that may suit me? Will the corellis play arco much better? Many thanks.
