Hi again,
Well, home made, but it's far from being finished ! My father (75 years old...) is making all the wood components (neck and body), while I'm working on the metal bits (tremolo, which is rather tricky, and roller bridge).
No, it'll be per original, ie 3 Trisonic PUs in serie.
Well, I guess you won't know until you've tried it ! That's what I will do (in the next few months or so), with the luck to be able to try different solutions, as the neck is bolt on, which allows me to test it out on different 'fake' guitar bodies, with different PUs and drivers positions. When I find (hopefully !) something working, I can make the real body. As I'm not an electronic wizard, I guess I'll have to buy a commercial solution (Fernandes sustainer) and try to make it fit to my guitar.
Pete, even though using a piezo to use as the driver signal source didn't work in your case, I might have a go with that solution, as it makes sense to me. Maybe I'll be more lucky ??
Anyway, thanks for all the advice.
Cheers.
Manuel.
