My son has a recording studio, and he does have some high end mics. I would guess he's got some that are much better than what I'm using.
I will probably head over there some afternoon with a few guitars and the TD in tow see what happens.
For now however, the results I do get with the AKG are absolutely an improvement to what the guitars sound like without the TD. I have a nice Taylor Nylon, but the expression system ESN is very hard to work with. The tonedexter made a vast improvement there.
My SJ200 and Taylor Grand Symphony have Infinities, they sound far more natural with the TD than without.
So over all, I am happy with what it's done,
The idea of trying to use a better mic is s really something I'm interested in doing. Plus I get to watch my grandson run around like a nut!
