Hi Bill,
I've taken the liberty to upload the picture linked to from
your other thread - every inch an Alembic, and some spectacular walnut!
The electronics appear to be the standard
Europa/Rogue package. You have a volume and a blend, then one filter with its trusted side-kick a.k.a. the Q-switch, plus two quick tone switches for bass and treble (cut/neutral/boost). If it were Signature, you'd have four pots (volume and pan, and two filters) and two Q switches (one for each filter). The setup with two filters is classic Alembic, but the Europa/Rogue package is perhaps a little easier to use.
Alembic electronics take some getting used to, but the sound really stands out from the crowd. The
Must Reads section points out some interesting discussions, if you want to delve into the technical side of things.
The neutral setting would be the filter fully open, with the Q switch off (in the up position), and the two three-way toggles in the middle position. Turn to blend pot to either end, so you get to hear just one pickup, then try out what happens when you gradually close the filter. Then flick the Q-switch and change the filter. Repeat for the other pickup, and for some of the in-between blend positions, for different right-hand positions, for slap/pop ... You have a really great scope of different tones, even before you start using the bass and treble switches.
Hope this anwers your basic questions!
