See this chart: http://www.shootoutguitarcables.com/guitar-cables-explained/capacitance-chart.html Think of anything below 70 pf/m as low capacitance (Works out to about 22 pf/ft). In other terms, it is often said that 20-30 pf/ft is a well liked "sweet spot" for guitar cables in the typical 12-20 foot range. But Canare GS6 which I like very much is in the 50 pf/ft range and favored by several professional touring musicians. It's tough, handles well, is great to build with and to me sounds just right most of the time. For patch cables, it's hard to make a rule as their cumulative length is typically too short to matter as much.
