Nice! I finished up a 12 bar blues in Bb. I"ll try to make recording and chart and put up links tomorrow.

Im working through that course too. It's a game changer. Keep us posted. Would love to hear how it goes for you.

this is great, thx for sharing. 

How do you like the DV Mark? I'm looking for something that doesn't add any color. I love the sound of my guitar acoustically, just need that sound louder (and some reverb) when I start playing gigs. 

I dont either. I had them on my solid bodies at one time when I was gigging with multiple guitars. Now I buy good quality straps ; keep the the tail connected and fasten and unfasten the upper bout. I might be worried about the strap-lock buckles that you install on the strap scratching an arch top.
