ive been searching for replacement pickups for an Epiphone explorer bass to brighten up what I perceive as a dark muddy tone. It’s been a tough search with very little success. After talking with a specialist at bestbassgear.com, I was informed that the Bartolini T4CBC is my best bet. By the measurements it looks to be a fit although not a perfect one but still a fit. I’m gonna try it out and let you know how it turns out.
