Sorry to bring back an old thread...Shaman, that is a gorgeous PC-1! Beings a lefty as well, I'm envious!
I have a custom guitar with the same sustainer as the PC-1, but I've been having a problem with mine. My neck pickup/sustainer driver won't work when the sustainer is off. Long story short, the culprit is the yellow transformer on the sustainer circuit board. I would replace the transformer, but there are no markings on it, so I don't know which transformer to order! If anyone could let me know what value that transformer is, I'd be very, very grateful.
The transformer is the yellow one part on the left in this picture:

I've seen a photo of someone else's sustainer that does have writing on the transformer, but it's too small to read from this photo:

But, I do have a lot of info on this sustainer, that PC-1 owners (and recent Kramer Sustainer owners--same sustainer) could find useful. Here is the basic wiring diagram I got from Floyd Rose with the sustainer back in the 90's:

I also had some correspondence with the main designer of this sustainer, Rick Knotts, a few years back about calibrating the sustainer:
The four pins not specified in the diagram: For changing the load on the bridge pickup. The difference is subtle. Check the sound of the bridge pickup with sustainer switched on and then off. Use the guitar chord you would normally use. If the sound is very close to the same, you can ignore the pins. If you hear a difference not to your liking, try jumping 1 and 2 or 3 and 4 (numbered consecutively).
The trim pots: One is for sensitivity and the other is for output. Turn the
output and sensitivity all the way up, then back off until the uncontrolled
feedback ceases. You will then have the highest possible output. You then
back the sensitivity down to whatever level you prefer based on touch.
Set the height of the driver as close to the strings as you can for the
best driver performance.
Unfortunately, he doesn't work at Floyd Rose any more, so I can't just ask him what value the transformer is! Here is the manual for the recent Kramer Sustainer, with a wiring diagram:
Kramer's sustainer manualI hope this helps anyone with wiring trouble on their PC-1's! If anyone can tell me that transformer value, I'd really appreciate it!
