A good starting point when I used to record:
KM84i for the neck
U87 or U89 on the body
Make sure you move them around until you find the best situation, and even more importantly, spend some time listening to the instrument from different places in the room and all around the body.
for pres we'd typically start with the old Telefunkens, but depending on how they felt that day they could be distractingly noisy.
Something like a Neve 9098 strip typically works well with acoustics, but I also used Earthworks pres on them regularly too. Bummer about not having gain control sometimes, but you work with what you got right?
