Short question for people with passive Sandbergs (standard Volume / Tone thing with Sandberg PU) – does anyone have any idea what exactly the Tone control does? I yesterday played through a new preamp with more headroom, and I had the impression rather than just rolling off hights, it also scoops the mids when fully open?
IANA tech, but IIRC the traditional passive tone control induces a resonant peak in the mids as you roll the highs off. So that would mean you didn't have that mid bump when it's fully open.
