I just ordered a Schaller STM, but I don't think that I'm going to be able to use it. It was an eBay purchase, to boot, so I won't be able to return it, either. I got it for my Les Paul (to match the new Bigsby B7 that I'm installing this evening), but the kicker is, I'm left-handed. The STM has slanted rollers to match the offset of a right-handed Les Paul bridge, and putting it on a reverse slanted lefty is only going to exacerbate the slant of the rollers. I've been looking at the schematics on Schaller's website, and I don't think that there's any way to reverse the slant. Bummer. I guess I'll just post it for sale on the Bay myself, and try to recoup some of my expenditure.
