1. Extruded Aluminium Body
Each Cluster module is made from one solid piece of extruded aluminium.
2. Threaded Strips
Though of course you can also use sliding nuts, if you want.
3. Wooden Cheeks
The wooden cheeks let you shape the case in many ways: you can go from East-Coast upright to Buchla-style curved.
4. Plastic Feet
Just like everything else, these can be added to your liking. The material makes them sturdy and gives adherence to the surface your case is positioned on.
