[OT] What if an active buffer is too bright? in Helix Posted April 10, 2016 there's nothing else going on. But again: Where in the circuit of the guitar the buffer is positioned? Between Pickups and potentiometers or after the potentiometers? Or are you comparing different guitars with different pickups? Each pivkup has its individual resonance frequency and "peak strength" and is influenced individually by pots and cables. This all depends on the inductivity and resistance of the pickup coils, how they are solded together and some other details as magnets, magnet position and magnetic materia (as steel) in the coil. Sorry that i'm perhaps a little bit slow in understaning, but a foreign language makes things not easier to me ;) It would be easy if you could pass by and we could measure your guitar and cable, but from Boston to Germany is not this easy.
