This was in MY STASH!
The block of wood is Fenders perfect fit and light weight but solid wood block to wedge in between the trem block and body. Thus making the Trem not usable, But Tone and Sustain CITY!
I have a few of these blocks in my shop. I use them. I have used other pieces of wood I come up with here and there. None make my Strat sound better than this Wood Block. Laugh all you want. The early Clapton with Lace Sensors and this Block HAVE BELL Tone!
All these parts are from a USA 99 Clapton. All this was in this bag in a box for I bet 10-12 years. In my many getting out of hand Fender crap all over... boxes of great parts...
