Here are some things I am really going to enjoy about the 16":
1. a greater sound range: 11 notes(maybe more) vs 8 notes.
2. faster building time: with the 12" I am doing some serious hard labor just to prepare the steel, while the 16" will be custom-shaped to my specific requirements; steel type, thickness, tempering, diameter etc. I'll enjoy more time fine-tuning and cutting and will no longer have to vacuum 1" of metallic dust from the floor on a daily basis.. no more wearing the painful respirator mask 8+ hours a day... mmmmm..... dreams...
3. Minimized effect on my health. Regarding the above-mentioned metallic dust <--- not good for the lungs :D
4. New discoveries, new frontiers and lots of fun. I really can't wait to have the first one ready.. Just gotta catch up on these 12" and begin taking orders for the 16".
UPDATE: I have added a paypal link to the Purchase page to allow interested peeps to get themselves on the waiting list for the 16" drum. As mentioned above, once I have caught up with the time-consuming 12" instruments, the 16" drums will be released and they will take much less time to complete. I promise they will sound amazing :)
