there are makers of low capacitance guitar cables for this very reason.and combined with the capacitance of the cable creates a filter that kills high frequencies.
about 30 years ago i had a guitar player ask me to build a clean preamp box for him. it was very simple, a TL072 op amp, one half used as a battery splitter (artificial ground at 1/2 VCC), and the other half as a noninverting gain stage with a gain control. wide open, the gain was 10, and it was a very clean sounding preamp with a very high input impedance.
