I did a search here first and didn't turn anything up that mentions what size Allen wrench is needed to adjust the bridge saddle height on a Strat.
I've gone to 2 music stores and neither knew. GC tried to sell me a Guitar Swiss Army Knife type setup with screw drivers and allen wrenches but still didn't look like it had the proper allen wrench size. A hardware store I went to had allen wrenches in a set and the smallest one looked like it may be close but with my luck it wouldn't be the right size.
It looks like I may to buy it on-line but I still need to know for sure what size I'm looking for.
