JSC: yes I am. The alu compton has made the guitar very resonant and alive. I love it!
My particular 5129 has an atypical 14" radius neck, so I had an alu made to match the 14".
TIs sounds even better with 2-3 times longer sustain on this guitar, but (to my knowledge) those are only made in 12" or 9.5".
I prefered the feel and already apparent improvement in tone of the alu on my 5129.
And my TI went on my country gentleman. That guitar (the CG) is my main go-to guitar now. I absolutely love the tone I'm getting from it.
