They have less high mid to my ear
I'm hearing something like that. Maybe need to roll with less bass/more treble than I normally would. Such a versatile preamp in that regard.
Related ... when I need that 'Jaco tone' on my flats-strung PJ5, I leave the VTC wide open, dime the bridge pickup, and roll the treble all the way off. Did that by accident and oh yea ... it was good. Ditto on goosing the treble and backing off the VTC just slightly to get a slap tone that slices but doesn't shave any eyebrows off with excessive treble.
