So the only difference between Electrum and CS is the 5-way switch Vs. the three toggle switches?. Then my much dreamed CD must be also a combination of both, since I?d rather go with the 5-way (maybe some push/pull knobs if needed be) than the 3 toggles (had a guitar like that once, and quite frequently found myself in Off/No sound mode after hitting them the wrong way... in the middle of a song.
Although not double locking (which would be my choice, Floyd-Rose double locking style), those Kahlers used to be quite good. I have a black one, the same exact model, on a Jackson Fusion EX (which was modded before I got it) and it was a matter of time before I got accustomed to it, and its setup, but it behaves nicely!
