Yes, sorry if I sounded a bit peremptory - I have a Sire M7 with that kind of switching. I use it, mainly, in parallel mode and never in single, switching only to series when I need the extra mids. It not being played much since I got my Tanglewater (Overwater by Tanglewood). The Overwater pickups seem to be in parallel, both on the above bass and my fretless and that seems to suit me very well.
