They’re made from by far and away the best cable on the market to date: the Sommer Spirit LLX.
 
Boasting the lowest capacitance out of all instrument cables, these breathe new life into your tone, letting you hear the “air” – the highs you never knew were there.
If you need uncompromising sound & build quality, especially for passive instruments, get yourself a DreamVibes Ion cable. The low capacitance will allow your tone to shine where lesser cables falter.
