IntroductionAbout This Course
Welcome to the Robert O'Brien Online Guitar Analysis and Testing Course. In this course, Robert invites Australian luthier, Trevor Gore, to show how to set up and run the tests he explains in his Guitar Design and Build books. Many people have asked Trevor about doing a video so that they could see how the tests are set up and done rather than just reading about them. This video course will help you avoid technical setbacks and shorten your learning curve when setting up the hardware and software needed to capture the frequency responses as well as measure the monopole mobility (responsiveness) and other critical elements of your guitar. Learn to do all of the major tests that Trevor does while building his world class guitars.
The course is not meant to substitute the information contained in Trevor's books but rather facilitate the understanding, setup and execution of the tests described in his books.
Learn about:
- How to set up microphones for testing
- How to install and calibrate Visual Analyzer software on your computer.
- Learn how Trevor made his custom signal generator (PDF file available in the downloads section)
- Tap testing for frequency response curves
- Using Chaldni patterns to verify frequencies
- Measuring material properties
- How to determine soundboard thickness
- How to measure monopole mobility
- How to measure degree of bridge rotation

I just bought this video course and it is a revelation. I've had your books for a while but this has given me a way in that I really needed. Thank you. Joss

×your classical guitar voicing and guitar analysis and testing courses along with Gore's books are some of the best purchases I've ever made!
Trevor’s Online Videos. I love these things! Elaine
Another thumbs up to you for doing the Trevor Gore video. With your advice I went ahead and splurged on The Book and not only immediately found a bunch of answers to my questions, but confirmation of some "odd ball" stuff I've been doing the last decade, which was incredibly helpful in stopping questioning myself and eliminating possible sources of headaches. I could probably spend weeks just going through your videos! I wish I had taken the plunge a couple of years ago when you published your video course and saved me a lot of time! Kudos! Kevin
I have purchased your courses on wet sanding and buffing with Jeff Jewitt, as well as the Trevor Gore videos on resonance testing. Thank you! They were both excellent and well worth the cash. Aaron
Will add my appreciation here too. There's a few vital VA set up steps that aren't mentioned in edition 1 of the books. The mic set up stuff is helpful too, especially as its explained for two different versions of windows. I must admit I dithered a bit over the cost - but put in perspective its about the same cost or less than another hand tool in the shed so I went ahead. Its good value i.m.o. and I finally feel that I have some proper outputs from VA. Thanks Trevor and Robbie. Richard
I just watched these, they're a good supplement to the book.Thanks to Robbie and Trevor! Jim
The videos were a godsend. I was getting ok results trudging my way through different operations. It made everything so much easier. Thanks Robbie. Really looking forward to finally taking the course with Trevor at Robbie’s shop. Kreher Guitars
I purchased the videos online from Robbie O'Brien and found this very helpful when setting up the computer to do the tests. Australia

I have just gone through the video of Trevor going through the whole process of analyzing a guitar’s responses. It is incredibly useful. It is not a criticism of the book to say that a video of many of the processes involved is very powerful. Words can only take you so far in describing these techniques. In particular the thorough description of using VA is excellent. If like me you have been getting only middling results in spectrum analysis this course is really worthwhile. In a quick session today with my rubber hammer I have got better results than any previous goes at this. I would seriously recommend people who are into an analytical approach to stump up for this course. Dave
I recently purchased the online video series and found it was very helpful explaining some of the setup aspects related to modular tuning and VA setup requirements after reading the Gore / Gilet books. Wayne
I have been reading the Gore books for awhile now and have never had great results with the tests. Then one sleepless night while tossing and turning, trying to figure out how to get the results I'm looking for, i was surfing the web and found your video. The price was a drop in the bucket for the explanations i received. Thank you so much for making this available. Anthony
Really excellent and a great review for those who have taken Trevor's course or for those who didn't get to attend. Well done Trevor and Robbie! Thanks for putting this together. I picked up some points I missed in the course, found some shortcuts and a few other pointers. Tim
Woohoo! I’ve been hoping for this one for a few years! Jeff
I attended Trevor's first course and enjoyed it very much. Unfortunately though, my memory being of a vintage age is not like fine wine and as a result much of the information that comes in is not stored permanently.? So it is very helpful to have Trevor's video to refresh my memory as I go through the process.Thanks for putting it together. Steve
