I did a repair job on a friends Yamaha 12-string using the Bridge doctor system. I took it to Strawberry one time and let Michael Lewis, our festival luthier,work on it.He refretted it,reset and adjusted the neck, but there wasn't anything he could do about the face and action at the festival.Love those plywood 12 string tops.

He told me about the bridge doctor and gave me a Stewart MacDonald catalogue to order it.I took the guitar back to the friend and toldhim everything and that the recommendation was to buy a new guitar.That wasn't an option, so I ordered the system,extra brass bridge pins, and new strings.When everything arrived, I took it all to my friends bar and assembled it all on a pool table while he fed me gin and tonics and a few tokes.Good lighting on a pool table.It only took a short time to do it and tune the guitar.

Played absolutely great.

It's really amazing to watch the face straighten out as you tighten the thing up.I had to come back several nights in a row to keep re-tuning and testing that 12.

He's still playing it and when friends come over and play it and see the apparatus through the sound hole, he tells them what it is.

I have a Japanese Wilson 12-string that I plan to convert to a mandocello and it's going to get a Bridge Doctor when I do it.
