It's kind of a moot point as I"ve got a bone saddle on there now... BUT
I was playing with the TUSQ saddle for the last 2-3 weeks (this guitar is about 2 months old), and I detected a nasally buzz or flat tone on the B string
Well lo I put my reading glasses on and I think I spy something on the saddle (where there is that 'boxed' out area for compenation of the B string

I remove the string and lo there is a nice little groove worn under the B string, and it's a rattling and buzzing in there. I file it a little (dish it out, so to speak) and it is better, but of course the action is all funny as it is lower.

I know TUSQ is hard, and sometime prone to grooving... but this was rediculour... a really deep groove and after not too much playing.

I don't know if I want to bother making good on the saddle (w/Dave at Guitar Adoptions) or Larrivee... as I've now modified the 'evidence'
It is always nice to have a spare saddle (tho if this is a habitual deal with TUSQ, I'd rather have a full blank vs. that spindly compensated form

whaddya think?

Forget about "making good" on it.  Tusq dents under the strings as much as any other plastic saddle, and they do it just as fast.  If they warranted it against string dents they'd have gone out of business long before now.

Now that you have a bone saddle just forget about the plastic and play your guitar.  In about a week after putting in bone I totally forgot how much worse it sounded before.

that's pretty much where I'm at

thanks for the perspective
