i want to put a black pickguard on my mia jazz bass (natural/maple). the store in my area was only able to get an 11 hole pickguard from fender. the 11th hole being in the middle above the neck pickup. so i starting thinking that this will look cool. my question is...will it make much of a difference in the overall tone of the bass? i know it's minimal, but i'm just wondering. also...will it be a big deal when/if i put the old pickguard on to leave the hole and have it covered by the old pickguard? please let me know. thanks.
