We each find our own paths, and those paths are informed by our experiences and goals, as well as our surroundings. You can't throw a stone in the hard rock and metal scene and get _that typical_ Dingwall tone. It works wonderfully well - obviously, or else it wouldn't be so used! So in that small slice of music that's being produced and made now (and the past ~10 years), it's always there. So I get the "I'm bored of it" angle.
Overall I feel those scenes (don't get me wrong, I've been playing in those circles, in original bands, for 20+ years now) are due for a big time shake up anyway. Someone like Nolly comes along and tosses a Dingwall shaped grenade in there and everyone takes notice, and work towards emulating it. Then after a few years of that, a high percentage of things start to sound identical, or at least similar enough to be, well, overplayed.
The beauty of things is, even with a DGTC loaded Dingwall, and even a Dingwall amp and cab, there's _so much more_ available right there at your fingertips. Just cos it can easily sound _like that_ (I don't even have to describe it, because everyone here knows what I mean), doesn't mean it has to. So it can appears both the "I want to sound like Nolly did in 2013" and the "I need something different". To each their own, and hopefully everyone is enjoying the journey. Any component in our signal chain - player very much included - can be changed to sound drastically different. We spend a lot of time talking mods, tweaking, and going off into truly esoteric directions in support of all of that.
People change, too. What I chase now is different than what I chased 20 years ago. The options I have now are almost overwhelming...
