Thank you for answering! I´m deciding between the Core World Percussion or just one or two regions. I´m very impressed by the audio demos and I found user reviews on Best Service´s website that are very good about your products.
If I could point out the main things that are missing on your website imo, they would be:
1- Direct links from the shop to the main product page with all its infos. Maybe a "learn more" link? Since I´m so anxious (lol), on my first visit I gave up learning more about your instruments just because the lack of in-depth information. Later, I decided to try again and look more carefully. That´s when i found the other main page. Of course, with little effort we can find it, but as i said, anxious (and lazy) people like me don't like to search too much to find things.
2- Another thing that would be great is a deeper walkthrough dedicated to each region of your World Percussion series. Your overview video is everywhere and teaches the engine well but it doesn't show all of your instruments. Not even half of it. Was a little frustrating to open up this video on South America´s page and see so little about it. Since there are many instruments (thanks for that!!!) and each region is also an individual product, individual videos would be great and would keep things organised. As a customer, i don't need nothing fancy, just a screen recording going thru the instruments and playing for a bit would be great. And then, put this dedicated walkthrough on its respective product page together with the main overview video (which is already there) showing the engine.
3- User reviews on each product´s page. Even the bad ones! Says a lot about a company (I found very suspicious when user reviews are only 5 stars on developers websites) and help us to know more about the product from a end user perspective.
Hope that helps!
