I have a lot of irons in the fire but still manage to occasionally find time to take on some repair and restoration work. Recently I received a Ramirez classical guitar from a client in Florida. The action was so high it was unplayable!  I was able to make this guitar playable again. See the video below of the repair. Here is a quote I got from the client when he received the guitar.

My guitar arrived today.  Incredible work on the fretboard!  Such a professional job the eye does not see anything different!  The action is so much better, and easier to play.  Thank you for your contribution!  I especially liked your adding another saddle to the guitar in case I wanted a bit higher action, much appreciated.  I'm keeping your notes in the guitar case so I don't forget.

Shortly after receiving this first Ramirez Guitar and doing the repair, I received an email from another person in Florida that saw the repair video I had done of fixing the Ramirez and he said, "I have exactly the same problem. Can you fix my guitar too?"
So, long story short, I did the repair and also made a video of the repair. (See Below)
Here is what the client had to say upon receiving the guitar.

Hi Robbie !
I received the guitar just now and sooner than expected ( Monday ). Wow, I’m impressed of the repair that you did as If nothing has been done.. Anyway, the sound is incredible and a lot easier to play than before. Now I can start playing it again after it’s been sitting in the case for so long. TY for a great job. 
Regards,
Rolan 

If you are interested  in learning repair and restoration, I have an online course that I have put together on the subject. Check out the Lutherie Academy website for this and many other videos related to instrument making and repair. 
I also have a Repair playlist on my Youtube channel specifically dedicated to videos about Repairs and Restorations I have done.  

Happy Building.
