Good morning all! I'm in a band that plays heavy progressive music and we're tuned down to C# Standard (Ab-Db-Gb-B-E-A). I currently have a Brice 6-String with D'Addario Regular Light Gauge strings tuned to C# Standard and the lower strings flop and buzz (to be expected). What gauges would be best for this tuning? I would like to try the whole Progressive Tension approach, but I don't know how to go about that. My bass has a 35" neck. Thanks in advance!!!
