As I (hopefully) near the completion of the search for my spector, I was very close to purchasing an NS Q4 bold on, when I noticed for about 125$ more, I could get what appears the be the same model, but neck thru.. Is it worth the extra money? Are there really any advantages to having a neck thru instead of a bolt on? I think I read somewhere that Spector discontinued the neck thru models, atleast in Korea, but I am not sure. Was there something wrong with them, or something? Any input would help!
