potentiometers/electronics questions

i tried posting this in the lutherie/modding section, but it didn't get much attention, so i decided to repost it here.

so i've been toying with the idea of building my own bass for a while now, and i have a couple basic designs, and i can even order the parts.

the problem is that i have no idea of what pots i'd need to order so i can get what i want.

basically, my designs call for one master volume knob, two stacked/cocentric knobs (one will be bass/treble, other will be low mid/high mid), and then a 5-way switch to switch between the pickups.

i have absolutely no idea bout k's or what ones i will need.

any pointers?

thanks

usually the preamp you buy will have the stacked pots along with the volume pot that you need.

the switch you can get from stewmac http://www.stewmac.com/shop/Electronics,_pickups/Components:_Switches_and_knobs/Lever-action_Pickup_Switch.html

250k or 500k will work fine.

ok, what about hz? what's the typical range for those that i need?

like i said, i'm completely clueless :(

Are you making your own pre? I don't know anything about the making of a preamp, but the frequencies you'll want to be adjusting are 40hz for the bass, low mids at around 300hz, high mids at about 800hz, and somewhere between 2 and 7 khz for treble.

I'd suggest maybe rigging up some trim pots on the inside of the cavity to adjust the frequencies that the controls adjust just so you can dick around with it and see if you like certain settings better than others.

If you're asking if pots have specific hz values built in, then no, they don't.



Hope I helped? If you do get a working preamp out of this, you should totally do a how to with schems and whatnot... I might have to take a crack at it myself if it isn't too much effort.

actually you did help, thanks a lot!
