Having purchased a 23 year old Epiphone EB-0 bass as a take anywhere no worries bass I then started to get into the sound and feel more but wanted to improve the sound - this pickup does just what it is supposed to - it is a direct replacement for the Epi bass pickup - my tech was most impressed about how well it fitted and was easy to install (so didn't cost me a fortune), he liked the sound and I really like the sound - if you want a 60's vibe this could be for you - you can also install it with a more complex wiring to split the coils and stuff - brighter sound, less volume, but I wanted and got the THUD!
I changed the original pickup on my Epiphone EB-0 bass guitar with this DiMarzio gem and I am very happy with it! I needed to modify little bit the pickup hole on the guitar body, but after that, the other steps were easy, thank to the very good original instructions, good figures, etc. After the incorporation, still have enough wires to change the wiring if I would like to try other sound, but the easiest wiring produced so nice, warm and quality new tone..... Simply good!
