I've had plenty of time to get the feel of both my TH-1 (one of the thin bodied with bellycut basses) and the TH-2 (think body with no bellycut.
I have to say I like the TH-1 more. To be fair, it has flats on it while the TH-2 has round wounds, but still I like the skinny neck on the TH-1 a lot. Wish I'd bought that black one on eBay a few months ago!
I like my black thin bodied TH-1 much better than my thick bodied cherry TH-1
I really enjoy playing my thin-bodied Bach. It is quite comfortable to play seated or standing. LOVE the thin neck on this thing! It is without a doubt easier to play than the Epi NR that I bought from Denis. The Epi is fine, but on the heavier/thicker side.
That Epi sure did have thick ol neck on it. It was nice with flats on it though and played well.
Since they came out I've seen one or two of the white ones change hands and one of the black one but the blue ones seem to have gone underground.
