Hey all! I'm just getting famiular with these basses and have one coming in on Tuesday. A EB4 that is. So, I'm wondering, what is the difference between the EB4 and EB13? Someone is selling a 13 here on TB and I asked him. He said EB13 has 2 humbuckers that can be switched to coil mode. From what I can find, the EB4 also does this. Can anybody clarify this for me? I didn't want to clutter up his classified ad trying to figure this out. Thanks for any help!
