Schaller. Install them on every guitar you own.
End of thread.
The schallers are good... got them on all of mine. One word of warning though, and this may seem obvious, but if you fit them to a THICK leather strap .. check how tight the nut is on a regular basis. The leather compresses and the nut can become looose... I nearly had a BIG one with my L.P custom... the nut and washer flew off and I just managed to catch the guitar before it hit the deck! I like beat up and old looking guitars ... but I didn't fancy one with a Whammy NECK!!! Lol....
Does anyone know some online stores that have Schallers in stock? I ordered some a couple months back, but every place I found had them on back order.
