Worked up this combo bass line/rhythm stab idea and it's one of my favorite things to play at the moment. Maybe it becomes a song somewhere? Loving the @guthrie.govan signature Charvel btw... It's not just for shredding.

In this live performance of Half of My Heart from the Beacon Theatre in NY, John Mayer can be seen playing a Rick Turner Model 1

I picked up the guitar from time to time at friends' houses, and I was always intrigued by it. It wasn't until I was 13 my dad rented one of my brothers and I an acoustic guitar from the music store. We were gonna take guitar lessons. Caption reads: January, 1991 - John has lessons every Monday with guitar teacher Al Ferrante at Fairfield's Professional Music Center. I remember I'd get home from school, play for the whole rest of the night, and just never really catch up with sleep. My mom set up a rule - 9:30pm - so I would play all the way to 9:30pm, then I'd have to stop.

John Mayer - Going Down the Road, Feeling Bad - 07/12/13 - The Cynthia Woods-Mitchell Pavilion

As seen in this picture from the concert, "Where The Light Is," he is playing on the D-41 during the acoustic set while playing "In Your Atmosphere." The absence of abalone pearl around the fingerboard near the sound hole suggests it is a D-41 and not a D-45.

Showing some unsolicited #martinpride since two of my favorite @martinguitar acoustics happen to be in the same room together. On the right is the uber-limited 00-45SC "Stagecoach" model, but on the left is a guitar that's still available, and a sleeper hit in the Martin lineup... It's called the "Mini" or "Terz" guitar, and it's the only miniature acoustic I know of that is built with the same integrity as a full-size model. I bring it with me on trips that don't allow for larger guitars, and it's what I call a "pocket song calculator." I can lay in bed and write/brush up on a song without having to travel with a larger dreadnought model. It's the brainchild of my longtime friend Dick Boak and I'm glad I opened its case again. I'd forgotten how great a guitar it is.
