logansrun and MB,
Thanks for posting this. Watched a lot of video on this, and am very intrigued. While not an insta-buy, it's definitely on my radar now.
By the way, according to their installation video, the blue tape is a temporary thing while you center the x-brace with the actual ToneWood Amp. Part of a pre-installation checklist if you will.
And about compatible systems, I found this on their site:
"Generally, we have had a very good experience with most under-saddle piezo pickups, Expression II systems (Taylor)* . . . " (No, I am not affiliated with this company, just a messenger; don't shoot.)
