Location: Steeler Nation, Hudson Valley Contingent | The preamp in my trusty 80s C. Balladeer has passed beyond the pale. I've got a new Op-Pro to put in, and I remember a thread years ago with instructions (and more important for people like me...pictures), but after a couple of wanderings through the search function, I still can't find it. Does anyone remember which one I'm talking about or have some tips? I remember they used modelling clay to mold a template to get the placement right, but that's as far as my middle-aged brain can get. |

Location: Thredbo, NSW, Australia | Patch, I'm in the middle of doing the same to my 1982 Folklore 1614.
Unfortunately I don't have the photos with me, as I'm travelling at present, but I can tell you what I did to get the position for the hole.
I removed the preamp and can from my U681T, placed a sheet of paper on the side and taped it in place after cutting it to fit neatly against the heel of the neck. I then cut a hole in the paper, which was then my template. I removed the sheet and taped it on to the Folklore and marked the hole on the guitar body using a white pen.
I then had a look at some of my other guitars and noticed they weren't all the same. Some were closer to the soundboard than others, and some were a little closer to the head of the guitar than others. This suggests to me that there is some flexibility. You could have a look at your guitars and see which one appears to fit the best and use that to make your template.
I hope this helps. |

Location: Denmark | bvince did it similar: http://www.ovationfanclub.com/megabbs/forums/thread-view.asp?tid=29... . Unfortunately the pics were at the ning site. Whats the trouble with the FET-3? Maybe it can be repaired. It is not overly complicated. http://www.ovationtribute.com/Ovation%20Schematics/Ovation_FET-3_Pr... Maybe a capacitor swap is enough.

Location: Utah | I'd get a piece of aluminum or tin to use as a template. Bend it to the curve of the preamp can and cut the hole in it. When the can fits properly and the template fits flush against the curve of the guitar body, it should identify the correct placement of the can.
That's a nerve wracking mod. |

| You might want to invest $18 in an oscillating multi-tool from Harbor Freight. In my experience it's the perfect tool for plunge-cutting holes like you'll need. I used one in re-building a traditional wood/canvas canoe and found it very easy to control in making some very precise cuts in the course of removing some ribs. You'll also find all sorts of uses for it around the house. I know that HF power tools aren't the best quality but this one is fine for home use:

Location: Denmark | Oh - btw. if anyone has a FET-3 that is out of work and that they want to part with. Don't throw it away, instead consider sending it to me, it could be fun to try to revive one of those. Send me a PM if you have one such. |

Location: Thredbo, NSW, Australia | Here's the paper template that I mentioned. The guitar is my Adamas 2081 
Here's my Folklore with the two positions marked on to it's side. 
I used the one closer to the soundboard. I cut the hole using a Dremel that Enowyd lent to me. Worked well. |

I was in the other room with the Dremel. Those bowls scream something terrible under the knife! |

Yes, it is! But it is the American format. If you print it 1:1 it is original size and will fit exactely. Othewise the messurement is included, if something will not work out.
