Hi, I noticed that the tone filters on my BB have each have a screw for adjustments. (Call me weird but I just have to examine the electronics of all my new basses almost as soon I a get them). What does this adjustment do? Kevin |

Kevin, i'm not really familiar with the Brown Bass, and I can't keep all the electronic variations straight... but I'm pretty sure that if you're looking inside the control cavity, at a couple of small blue cubes with a slotted white circle in the middle, then these are trimpots to adjust the gain of each pickup. They have nothing to do with the filter(s). The idea here is that you can adjust the pickup heights (and angles, in various ways...) to suit your tone preferences, and then tweak the trims to balance the output levels of the two pickups in whatever way you might prefer. Adjusting the gain of a pickup via the trimpot is exactly the same, in terms of tone, as adjusting a dedicated volume knob for that pickup, or turning the pan knob (depending on what you have). Changing pickup height and angle(s), however, will alter the sound in different ways, so it's nice to have this flexibility. -Bob (edited) PS - I have custom electronics, and my trimpots happen to be backwards (don't know if this is typical): the one closer to the bridge controls the neck pickup, and vice versa. But you can easily hear the volume change with less than a quarter turn, so it's not hard to figure out. (Message edited by bob on January 04, 2004) |

Adding to what Bob said; if you've adjusted your pickups to different heights for tone reasons, you can use the trim pots to balance the outputs of the pickups to each other; and if you use two or more basses throught the same amp, you can use the trim pots to balance the outputs of the basses to each other. |

Doh! You're both right of course. I thought they adjusted the gain on the tone filters but they're wired to the volume knobs. I'm just not used to having two volume controls. My BB has the anniv. elec., BTW. Kevin |
