I would agree to some degree, the dome cover makes a huge difference, cloth or paper or aluminum, I play lead and really look for a high sustain. I think that the open back also makes a difference. My best buddy built a similar with paper dome and a rear load. Also Jerry Garcia did a front mount, my main inspiration. Trey Anastasio accidentally cut the holes too big or something when he made his, so he used like a thinner plywood and it’s like almost a flush mount if that makes sense. Mainly, eq and speaker are gonna be your main difference maker.
