I bought these bolts along with an ABM bell brass bridge and aluminium tailpiece. All the parts are superbly made and have added significant sustain and clarity to my guitar, (a 2001 Japanese Love Rock LS70), the change is quite remarkable, obviously the change is a combination of all these parts. If you buy the tailpiece then do buy the matching bolts, the fit is snug with little or no tilt on the tailpiece.
Thomann and ABM were extremely helpful in helping me select the correct parts. However it did highlight one irritation, the tailpiece is supplied with US threaded bolts and I needed metric bolts, as I'm sure many people do. It seems silly to supply the tailpiece with bolts it just makes the tailpiece more expensive by £20.00 (UK Pounds). I actually wanted to try the aluminium and brass tailpieces but it would have cost over £140.00 (and I'd have had 2 sets of bolts I don't need). Whereas if they were sold separately I could have bought both tailpieces and a set of studs for around £100.00. As it is my tailpiece and correct bolts cost £80.00, it's a lot.
Would I pay it again, YES.
