Owners is not the same set as customers, nor is it the same set as forum members. First thing to do is identify what group you really want to profile.
For example, customers, at least to me, would be recent/future purchasers of new instruments. Based upon the price, you aren't likely to find too many young people of either sex buying new.
Owners, on the other hand, would include all the people who have been able to acquire an Alembic through any means. All the sub-$1000 Spoilers and Persuaders allow this group to be much more varied in age and income. Do you include preamp owners as well as the instrument owners? That might spread it a bit wider.
Forum members is an interesting group. It includes both owners and potential customers. It even includes people who are in neither category. If that's the group you're looking to profile, I would look at a few dozen profiles at random. I would be surprised if you told me that as many as 10% of active forum members were female. Maybe it's just not obvious because of the nature of the topics discussed, but the names and pronouns seem almost universally masculine, Mica excluded of course! I would also suspect that the vast majority of participants here are instrument oriented. There are quite a few preamps out there that are owned by players who probably wouldn't be interested in participating here.
just a few thoughts from my perspective, anyway...
