Being part of the MTP I think it has been going awesome. This can open up the MTP in a direction that everyone can participate it.
I see this going to a structured or tiered system if people are involved. It can get the newest people in on mentoring onto the experts.
For example.
1.Fred signs up to GMC (Interested in being Mentored)
2. Fred needs to learn about the guitar (Scott has already went through this and can mentor the new blood)
3. Scott completed and needs to start learning theory and basic rhythm pattern. Dave just finished that and can Mentor Scott.
4.Dave just complete theory basics and needs to learn advanced theory and introduction into lead playing. Dan just completed this and can mentor Dave.
5. Dan just finished advanced theory and introduction to lead playing. Wants to begin learning advanced solo techniques and advance improvisitaion skills. This can introduce them to Muris, EMir, Pedja, or any instructor that can teach a specific style of playing.
It can be cool and has a lot of potentional. It also can be structured where there are mentors that teach specific aspects of playing. One mentor only teaches theory, another only teaches technique.
ANy way..
