Drums.

The O7 drums were designed out of necessity. I couldn't afford traditional drums in the numbers I needed. The idea started with Marte Ciro, a drummer friend, and from there I began experimenting, simplifying, testing, and refining the design. The goal was clear: to create enough drums for a big group, using as little material, time, and craft as possible, without losing strength or sound. The result is a drum that’s bold, practical, and built for real-world use.

Origins

Origins

I wanted to start my own drum project after I left Toca Rufar but I had no money to buy enough drums. The original idea to use drainage pipes came from Marte Ciro, a drummer friend who actually had a few that he built him self. Marte Ciro was kind enought to let me use his drums to start the project.

African techniques

African techniques

I got my hands on lots of drainage pipes, a few drummers donated used drumheads and rope was cheap enought, so I started building. The first batch followed the traditional rope techniques used in african drums to create tention. It worked well but it made me need more material that I could have. Besides 2 drumheads for each drum I need two extra rims to create the tension that could either be bespoke using some kind of metal or it could be the rim from a damage drumhead. I needed a better solution or I wouldn't be able to build the number of drums I was aiming for.

Japanese techniques

Japanese techniques

Eventually I found a way to make them so there was no need for so much material. This time using techniques inspired by the japanese taiko drums. Making holes on the actual drumhead didn't seem very logical but it worked. Still wasn't the final design but it was close.

Final designs

Final designs

After a few years of experiments, trials and errors eventually I got to a final design, I think. A mix of traditional techniques and a couple of new ideas made it work.
