i never seem to use the passive tone control on either my precision (doesn't even cross my mind), or on my jazz bass (sometimes i want to mellow out the soloed bridge pup but i just squeeze in a little of the neck one ; and i then get a little less hum as well ) . just wondered how you guys use them if at all. feel like i am missing out on something . also i am putting a bass together and it would be kind of convenient to leave out the passive tone. what you tink?
