Joining Tony's Acoustic Challenge and becoming part of the TAC family of guitar geeks was one of the best decisions I've made in my 5 decades of playing guitar. These are the things that keep me coming back. First the Daily Challenges: These are the key elements of the TAC method foundation of developing a guitar routine that works for you and implementing it on a regular basis. Playing for even a short period of time on a regular basis builds skill, knowledge and techniques. The Daily Challenges are presented in so that one builds on the next throughout the week. They are also fun and digestible. Second is the TAC community: this group of people is very supportive and encouraging and willing to lend an ear or advice if it is needed. The Forums: the community interacts through forums that provide an opportunity to learn what others are doing and see what they are playing (via video posts of performances). Finally the courses: Skill Courses abound for most anything including playing styles, knowledge building and technique building. I feel I am making great progress towards my 90 day guitar goals and am seeing real improvement in my knowledge and playing ability after just 2 months. TAC is great and I would recommend it to anyone out there that is looking for a way to start, restart of improve their guitar journey!
