Have a MM Stingray with 3 band EQ and Piezo bridge and I am a finger and thumb player. I am having a problem when I am in the upper range on mainly the D and G string but it is also weak when in the upper range of the E and A stings too.I have tried dialing in the EQ and nothing helps Ive tried adjusting the pickup but nothing seems to help is it my amp or is it my bass. My other problem is when I use the piezo pickup even with a blend I get a nasty clicking noise and I am to nervous to adjust it was hoping for suggestions.
