possibly i have just tried putting a small strip of electrical tape on the bottom of my saddle that seems to have cured the problem
cheers for your feed back mate
IMHO, what you want is an even pressure across the UST (
Under
Saddle
Transducer)....if you use electrical tape on the bottom of the saddle, you're "isolating" a bit of those vibrations from the pickup....and not getting all the sound your guitar can produce.
My suggestion is to get a piece of single strength glass (or, even better, double strength) and tape a piece of wet'n'dry sandpaper to it. Then take your saddle and rub the bottom across the wet sandpaper....the glass will be perfectly flat and provide the surface your saddle needs to be flat once dressed in this manner.
.....imagine if ALL of the strings were as "loud" as that lower E string....yes, that's what you're looking for

.
Good luck....as long as you're fiddling around with your saddle, why not get a bone saddle blank and fit that to the slot in the bridge? That will make a huge difference in the sound of your Washburn.
