Re: Estimat price for jem on ****.
I wouldn't expect much beyond the combined value of the parts. The odd thing about customs is that they are invariably worth the most to the person that dreamed them up and/or brought them to life, which often makes them difficult to sell. Somewhere out there, there is likely to be another person who thinks the guitar is worth what you think it's worth AND has the means to purchase it. However, the trick is finding that person. And I believe that most people on that auction site are looking for Ibanez Jems, not custom guitars made to vaguely resemble Ibanez Jems.
Frankly, I personally have a big problem with using the name "Jem" in conjunction with this or any other custom guitar. But I guess that's just me.
