I just know what I read/view in their eBay listings:
Example 1
http://cgi.ebay.com/EDEN-Bass-Guitar...em140094366735
* a 4-string P-bass is NOT a standard 22-frets, it is 20
* the neck pocket heel does not appear to be the Fender half oval
* 7/8" is significantly deeper than the Fender standard of 5/8"
Example 2
http://cgi.ebay.com/EDEN-Bass-Guitar...em140094381163
* a 4-string J-bass is NOT a standard 22-frets, it is 20
* the neck pocket heel does not appear to be the Fender half oval
* 7/8" is significantly deeper than the Fender standard of 5/8"
* that's Ash???
Example 3
http://cgi.ebay.com/EDEN-Vintage-Tin...em290091371959
* their standard neck is 21-frets ... but the body is 22???
* not a standard Fender style half elipse heel
* about as close as you can get to copying a Fender visually, but they are somehow getting around the need to be licensed to use the headstock design
From what I've seen being offered on eBay, I'd stay clear of this outfit.
all the best,
