Hi Matthew
i was hoping for your answer, since some of our luthiers are for some days engaged in the ISB show and obviously away from their computers.
I tried a G string with less tension, a Corelli 370 F, and the bass responds much better than the Spirocore Weich G. I restrung it with the Corellis but the rest of the strings were not so loud, so i put the Spiros back and left only the Corelli G. It seems that this instrument needs less tension in the G string, so i desided to proceed for a high saddle. I'm planning to do it in the first days of July and keep you posted. Meanwhile any other ideas are welcomed.
Mike
