I will admit that modding can possibly get addictive if you start something which leads to changing or swapping out another part...and another part...and another part lol but, in my case I kept it pretty simple and easy on only one bass (my precision) and the changes have been outstanding. I swapped the pickguard, factory stock no name 70's tuners to Hipshot HB2's (also adding an X-tender to the E key), swapped out the SD QP with a EMG GZR, and finally changed out the stock bridge with a Badass II. The best part of these changes is that no extra holes had to be drilled, no new routing, no alterations to the previous factory stock setup.
