So I'm buying another Tremsetter for the FR on my Tele, I've just got it playing really nice (well a while ago now) but it's being a bit problematic coming back to pitch (I like how loose it (the action) is but pitch is king here). I've had a Hipshot Tremsetter in my Anderson for ever, IIRC I bought one as soon as they came out. They do make the action of the Trem a little stiffer, but you get used to it quickly, they do also bring marked benefits in keeping in tune and greatly reduce sag, flutter etc.
So I'm ordering one online from them, and the postage is just out there ($83 for a $48 part ?? hopefully they'll look at that and get it fixed), but emailed them and they got back to me very quickly and we'll sort it out. for my order, so very nice people, and I'd
highly recommend the Tremsetter (http://store.hipshotproducts.com/cart.php?m=product_detail&p=115) to anyone using a floating trem where it can be installed.
