This question is for alembic f-1x owners and others familiar with this pre. What do you set the preamp's volume at? I wanted to know if I should adjust the volume knob on the Alembic or level on the power amp. Since there's no gain knob or light on the alembic, I don't know at what point the preamp is getiing an optimium gain level from my bass. I've messed with it alot and I can't really hear an audible difference until I max the volume out. At that point, there is a bit of overdrive. Anyone have some info on this?
