Okay, I really like the comfort and feel of this bass. http://indieguitars.ca/product-2.cfm?ID=36
I've only ever switched out pickups on guitars before, and even then it was always like-pickups. Single coils to singles, etc.
If I wanted to change the pickups in this bass without any routing, what options do I have? Do I measure the covers and hope that makers install their coils inside the same shapes? I understand the preamp will be the biggest thing shaping the tone. Do preamps have to be matched with pickups? If I get a bartolini preamp does that mean I need their pickups as well?
What else is there to look out for? Thanks
