This is a wonderful invention Esther! I think people who want to start a band or play their own music live would really appreciate the All In One Geyums so they could perform everything themselves and enhance their instrument skills. Your invention looks fantastic in your drawing and you've placed the different instruments really effectively for ease of use, I think seeing a performance using your invention would be a really interesting experience! Thanks for your creative and practical invention, I look forward to your next one!
