I've just become the happy owner of a Purpleheart Persuader and a Quilted Maple Spoiler... I guess we can call them the Misfit Twins. Attached picture is not my rig and the basses are both 32", despite the perspective skew.

Persuader questions:
I always peek in the cavity of every new bass I buy and in the Persuader there's a loose ground wire capped with a wire nut. Doesn't seem particularly "Alembic" but the wire, at least, seems factory. Any thoughts on this one?
I'm curious about the single pickup with volume and filter. It seems to have a Q boost - is it possible to add the 3-position switch for selectable Q boost?

Spoiler questions:
I was excited for the Spoiler because it has the three witch-hat knobs and I assumed that meant it had a blend knob. It's not, it's a pickup selector. I'd prefer to have a blend knob... does anyone know what that takes/costs?
The Q boost switch is 2-position - can that be switched out for the 3-position?
Are the two blue trimpots gain for each pickup?

I was looking at that bass. Eric got it for a steal off reverb! Love that purpleheart top.

Yes you can order a three position switch for the Q.

Congrats! One doesn't often get a steal on Reverb nowadays.

Great pair of basses!

Again, yes to the 3-way Qs.Pan can be done.Trim pots - yes, gain for each pickup.

Enjoy!
