volume resistors

[manchild]

How much louder percentage wise is a 1m volume pot or straight wired compared to a 500/250k when on full?

That would depend on the output impedance of the pickups.

Is there no way to make an approximation? If a pup has a 250k res, and you swop it out for a 1m or wire it straight, and leave all else the same how much of a volume increase would occur?

Well, you cannot come up with a precise, definitive answer, as the percentage of amplitude change with 250K, 500K and 1M ohm parallel resistive loads would change with the circuit's impedance, and therefore, be based on the specific pickups in question.

You could, however, probably come up with an estimate that with average (X pickups) you could expect however many decibels increase or decrease in amplitude.

It's a much easier idea to simply try it out. Pots are cheap, and if you can solder, it's only a few minutes work to swap them around.

If you have X pickup and it has has a 250k pot - if you change it to 500K, which number would you need to turn the volume down to (1-10) in order to get the same output the 250k has at max (10)?

it won't really be louder at all, just brighter.

also, you can't turn down a higher-rated volume and sound like a lower-rated volume. it's not the same.

you can do that with the tone pot, though; a 500k audio taper tone dialed back to like "7" or "8" would be like a 250k tone on "10".

Here's an idea:

Since you want to make this base with no controls that acts like it has controls (if I've got that right), why not wire up a bass using trim pots?

You can tweak them until you get a sound you like and seal them up out of sight.

Just an idea.

Hey Snake, now that sounds like a great idea, as i dont have much experience with this, i wasnt aware of the idea of pots without ext control...

Think that pretty much solves the prob

Cheers
