If it has the proper preamp, it's probably VVF, you might change it to VBF, possibly adding a second preamp (the Pan Preamp kit). And you might want to add a Q switch (as it is, it's most likely to have the Q boost on all the time) and those come in a 2- or 3-way format.
If there's enough room in the cavity, you might change it for Signature or Anniversary.
