IMHO, Keystones and Signets are USA Luddies for the working musician.That's why the new Keystones are so damn interesting. USA made and crazy affordable prices.
Classic Maple is a step up in the availability of configurations. Legacy Classic is a take on the vintage shell formula and provides an aspirational level, while still less than a DW collectors set- difference in labor in NC vs CA perhaps-plus a little more for DW being trendy??
This new Mahogany may be Ludwig's way of competing with the higher priced kits.
There are some who think more expensive=better.
I agree with previous threads on here- better to have a less expensive drum shell with better heads and spend $$ on pro grade cymbals.
That being said- I'm sure the new mahogany drums sound great and if you have the bucks why not?
We live in a time where great drums are available at a lot of price points in all manner of woods and other materials.
The first one to get a set of Legacy Mahogany's please post pics and sound files!!
