bar none ...are the new Kramers...
My first experience with cheap Chinese shredders was a Dean 350f. It was a $300 basswood bolt on with a FRS trem. That was almost exactly ten years ago. It was probably made in a similar factory to the new Kramers.
At the time, my nicer guitars were out of sorts, and I wanted a 24 fret guitar to play some shred songs I was working on. I upgraded the trem block to an OFR block, and that was the first guitar I leveled myself.. which came out great! It was my main guitar for at least five years.
The frets on that were medium or medium jumbo, with soft metal. They wore down and I leveled it a second time, still a great playing guitar.
But I realized several years back that the guitar neck was taking a bad set. Too much relief at the heel, not enough farther down the neck. I leveled it one more time, but had to chop down the upper frets so its not really comfortable for shredding higher on the neck.
It is technically playable, but its pretty much junk now. The FRS doesn't return to zero as well as it did. Its ugly. And the neck/frets need to be replaced. Its a throwaway guitar. I want to fix it up just because of how much time I spent with it and because it did have a nice sound.
The moral of this story is that these cheap guitars aren't built for the long haul. They use cheap, soft fretwire of smaller dimension (medium). The necks are likely not reinforced so they will distort over time, and when it comes down to it, they are homely compared to more expensive guitars.
