Re: Similar necks to 88 JEM 77FP
I haven't played any of the Nitro necks, looks like they are mostly on the metal guitars like RGDs and Iron series - I'll keep a look out for them.
I played a bunch of Jackson Soloists yesterday, those necks were quite good, not painted like most neck thru necks. The non quilted maple top ones had rounder more C neck than the JEM but close, the maple tops had more of a classic flat RG D shape. Really good for shredding too. Of course couldn't match the complex tone of the JEM 77FP with it's original PAF Pros.
So far they are my best non Ibanez option of comfy necks.
