I have a 300 and a 500 and i am in general pretty happy with both. Sometimes i have the effect that on different notes i get a louder banging sound, almost like the piezo is resonating in the saddle. While playing clean or acoustic sounds it's more obvious. Different notes on differnt strings . .
Is this effect known? Can i fix this by letting some superglue sink into the saddle? If i change to ghost saddles, will it be gone?
dont put super glue in the saddles . ! youll have to replace the whole saddle if the pickup dies and 2 you could break your ground connection that way.
as to graphtech. there better but until you figure out whats causing this i wouldnt go that route.
