Can somebody help me with this issue, of not understanding. Andrew Gouche' States he tunes down to D'. And of course he plays an MTD 6 string his very own signature. So I need help in understanding the over all tuning of the strings, If it's not standard tuning of B' E' A' D' G' C'. What formation of tuning would take place in the way he's tuning. Thanks. To all bass players no matter what style of music keep holding down the bottom end. Be Blessed.
