I've had the opportunity to play on the VAD306 and it's quite a remarkable set. The pads feel incredibly realistic, which is a major plus if you're used to an acoustic kit. They respond well to different playing dynamics, so you can really express yourself fully.
The sound quality is excellent; Roland rarely disappoints in this area. The presets are diverse and should cover most of your needs, whether you're practicing at home or performing live. There’s enough variety and quality in the built-in sounds and effects to keep things interesting.
In terms of setup and durability, it holds up well. It's sturdy, which gives it a good feel but also means it should last a long time even with frequent use. Setting up might take some time initially as you acquire everything adjusted just right, especially if you are meticulous about your drum layout.
Overall, based on my experience and what I’ve seen from others who own it, the VAD306 would be a solid choice for both practice and live performances.
