Hi everyone. I recently had my jazz bass fitted with a big chrome humbucker that would find in the neck of a Gibson bass. I was finding the jazz a bit thin sounding compared to my 57 p bass reissue, i also thought it would look really cool and quite unique which it does. As expected it now sounds massive. Very fat and full ~ except the low E string which is just quieter than all other strings.when fretted it's pretty much ok (although still not as thumpy and full as the p bass) but when open theres a big lack of volume. Has anyone else any experience like this? Any suggestions? I think this thread may have ro go in the setup forum as im suspecting it may be the nut but it was fine before the mod. Pick up height all ok. Thanks in advance.
