So if the intonation isnt correct that can affect dead spots? I thought that dead spots were caused by the wood in the guitar was resonating at the same frequancy as some notes, and that caused the string vibration energy to transfer to the wood making the note die faster. The intonation is a little off though, so I might fix that. Other than that I think it´s set up nice. I dont wanna mess with it.
It doesnt bother me much any more though, to my experience it seem to be a very common problem with sg´s. But it would be nice if it werent there. I thought all guitars had dead spots, more or less prominent?
