The TENET Guy
It is true. I know some people are quite excited about Evertune and it does seem to do its thing very well. But much like roller bridge saddles and similar inventions, it is a bit of a gimmick and shouldn't be necessary unless you're compensating for construction or hardware problems that are happening elsewhere. That's of course also the reason why they don't become standard tech that is used by manufacturers across the board.
I disagree about it being a gimmick or not necessary, the Evertune solves a ton of problems that modern metal guitarist run into and it allows you to get away with stuff that is just not possible with a normal fixed or floating bridge, Evertune allows for severe down tuning while also giving you the ability to use lighter string gauges on a normal or even shorter scale length guitar and you won’t have the note go sharp on the initial attack, you won’t have to raise the action of the strings, and you won’t have intonation issues either. That’s just not possible any other way without having the change something in the setup, but with Evertune you can do it no problems
If you’re play in E standard then yeah, you probably don’t need it, but for us metal guys that down tune really far it’s a must have. Misha from Periphery tunes down to Drop C with the low C tuned down to G for Reptile and he uses a 10-58 for that, normal that string gauge would be way too light for that tuning on a 25.5 inch 6 string, but with an Evertune they have no issues at all
