I have this idea of making a pedal that will take me from tone all the way down to all the way up. I play with my tone all the way down usually, and this pedal will be used to give me the ability to give myself a tone boost in a second, since I don't have much time between parts to change my tone knob, and since I can't do it fast enough with a switch on my bass. So how can I build this? I was thinking a push button switch wired to a pot that's turned up all the way, but is that how it would be done? I'm also not sure how to wire a push button switch, so anything would help. I also would like a led but that's optional
Have you ever given thought to a treble booster?? VFE has a pedal called the Focus I think. Its a boost that has an EQ on it. That may get you what you want..... http://www.vfepedals.com/focus.html
With the tone up (trebly) you're basically getting a naked signal. All frequencies leave the bass from your pickups. Passive tone control is a high cut circuit in most cases. Roll the tone down and you're removing frequencies that would be there otherwise. You could not do as you suggest, have a footpedal tone knob to re-introduce the high frequencies, because you removed them at your bass. The reverse would work, have your bass with an open trebly tone, and use a passive tone circuit in a footpedal to get that bassy 'tone down' sound I would suggest installing small switch on your bass that bypasses the tone knob on your bass. Bypass tone knob = open (trebly) tone knob, so set it to tone down and bypass for instant tone up
I've tried the switch. Worked like a charm, but not as quick change as I would like it to be. But, if I have the tone all the way up on my bass, I could make a pedal where it would cut out the tone? That would work for me as well.
I think it would You wouldnt even 'need' the knob if you don't plan to change the setting, just a cap and resistor. Search for passive tone circuit bass

I don't understand how rolling your tone knob with your pinky wouldn't work for this. Not trying to poop in your cornflakes, whatever floats your boat, I just don't see why you would need a pedal make completely rolled off to wide open knob adjustments. Good luck in your search.
just get an eq pedal, adjust it to your normal rolled off tone with your bass control trebled up, then when you need the boost, kick off the eq, instant wide open tone.
