I'm planning to build a custom P Bass and I will love to use a Geddy Lee neck that is available for sale. I already have a GL signature J Bass and really like the profile of her neck. I searched TB and found this thread: http://www.talkbass.com/forum/archive/index.php/t-246462.html It seems like P Bass and J Bass necks are interchangeable. Can anyone confirm if I can use the GL signature neck in a P Bass body without problems? Thanks.
