Spectraflex cables?
I used Monster Rock cables for years, still have them and like them. After building a new pedalboard with George L stuff, I tried a Mogami cable into my pedalboard, and noticed a lot more brightness and clarity compared to the Monster, as if I'm using a BBE Sonic Maximizer. I'm readjusting my eq settings to get my bottom end back, but the Mogami sounded like it was louder or providing a stronger signal.
I read, and I kind of agree, that expensive cables matter only if you're going a very long distance directly into your amp. If you're plugging into any pedal that has a buffer, it doesn't matter what cables you have between that buffer and your amp. At least that's what the guy that created Pedalsnake claims, and after using his cable from my pedalboard to my amp, with a Mogami from guitar to pedalboard, I fully agree. Based on this principle, I don't know if active pickup users should see and difference, unless their cable is poorly shielded to create noise
