I'm looking to change the preamp, and possibly the pickups in my USA Deluxe Jazz as I find the standard setup is very limited, it may as well be passive with the tone control stuck on full. It's the late 90s - mid 2000 model.
Has any one swapped over to another preamp and did it make a difference?
I'll probably go Dimarzio Model J for the pickups.
Thanks in advance.
