The other thing is Denny personally signs each of his guitars with a felt tip pen ... who wouldn't want that??!!
Gene Simmons even plays one ...

They're made by Sigma so probably decent though I think the extra light strings are a big part of the equation/science but I'd be curious to know if they are built with lighter bracing specifically for the extra light strings in order to still sound decent.
These are right up my alley, only place I've found them is on eBay though.

I think after so long (me about a year) you just want a different tone.
Different strings and picks would get you some change.
I like Elixir Nano PB's strings and Dunlop Nylon picks ...
