I now have an eighties Foundation, A rosewood and a maple necked early nineties Foundations(SFs), 2 maple neck mid nineties(soapbars), and I just traded for a Fretless Foundation 2000. I like them all, but I am not sure I understand some of the changes peavey made.
The F2000 has a high mass bridge with bridge or through-body stringing which looks like it is probably much more expensive to produce, but the pots are the little dime sized parts that are very cheesy and allowed a great deal of interference. I switched them out, but when I did I noticed a difference in the pickups. The earlier soapbars had a separate ground that was soldered to the pots. It is not present on the F2000, this also seems to contribute to the interference. I know others have complained about noise when soloing a pickup on a Foundation, but this is the first time I have really noticed any hum.
I do like the five bolt neck joint without a plate, but I wonder whether I will miss the tilt mechanism? In general, I am very pleased with my new acquisition, but I am going to have to spend some time working out the electrics. I'll try to add pictures in the next couple of day, but I just located the digital camera, and the batteries are dead
