1meg ohm pot wiring

[newamerikangospel]

WTFBBQ!!!!

So in the spirit of commercialism shrouded in the celebration of christs birth, but marred by the fact that he wasn't born in winter theolically, I bought by brother a 1meg ohm pot, since his bc richs' crapwood body is eating the output of his sh6. My question is, if I wire the 1meg ohm as the volume, and use the standard mini pot (250 I think) as the tone, will that dull the effect of the impedence boost?

You're going to lose some gain and treble, yes.

Now, one thing that you can do is no-load the pot by taking it apart and scraping away the conducting stuff at the 'full-on' end of the pot's travel - this will give a point at which there is no change due to the pot's presence at all.

I'd just get a 500K pot. They're two bucks at Radio Shack. Might as well trick everything out, I'd say.

Oh, and... 'theolically'?

Why not just get a no-load pot?

 

[JBroll]

Reason one: Not available at Radio Shack.

Reason two: No-load pot from GuitarElectronics.com sells for $7.95; 250K pot from Radio Shack sells for $2.95, and no-loading takes all of three minutes.

Thats obscene. We sell them for £2.99. Since everything in the US is cheaper, tahts equivalent to you guys paying $3 for one.

Wow, lol, it was supposed to be theologically.

And wtf, I thought the 1meg ohm pot would increase induction. So less resistence is better?

 

[Stitch]

Induction doesn't come into it anywhere.

Theologically means to do with the church/or a religion - i.e a theocracy.

Sort your words out man!

It was a joke, because alot of christians dont celebrate christmas on dec 25. In the bible, the sheep were in fields (which points to spring, summer, and fall) and he was born in a manger (which would not be possible since it would be too cold). The theory is that when constantine united the roman empire under one ceasar, that he converted pagans by placing christian holidays to correspond with their holidays (kind of saying "hey, its not really that different").

So a pickup doesn't use the string to interrupt a magnetical field, causing magnetic induction?

The basic science behind pickup function is Faraday's Law of Induction. It states that a changing magnetic field causes an electric field to be set up in a nearby wire, causing a current to flow if the wire is part of a closed circuit (a loop of wire for example).

Atlantic Quality Design, Inc., How do guitar pickups work?



And from what I remember (fairly elicitly I might add) of the fouth grade (primary school for you brits) experiment with the nail and the copper wire, is that the more wire coils you had, and the bigger the nail, the more current you got. So more coils=more resistence, so a 1meg ohm pot should up the output (also from every forum I could pull up by google, it said it did as well).

My question is, do pots work like speakers. two 16ohm speakers=8 ohm load, so one 1meg and one 250k=725ohms?

A 1meg pot will brighten up the signal and increase output, but not uber dramatic or anything.

It will allow you to have a much more finite control over the volume, however, and thats why I plan on upgrading some of my stuff with one.

i.e.

500k

500
400
300
200
100
0

1000k

1000k
900k
800k
700k
600k
500k
400k
300k
200k
100k

Both 1000k and 500k at max are outputting the relatively same level of signal, but the decrease in signal as you roll down the pot is much more smoother on a 1meg pot.

 

[JBroll]

... Much more finite?

Okay, so I talked to 7dt (many thanks) since I was minutes away from going to a foreign land (my brothers house) to install it. In the bc rich, with a 250k tone pot, it made a noticeable difference through his little practice amp. Of course, his little 8 inch speaker is going to react to the increased high range more, but it felt like a blanket was removed from the amp (what alot of people say about a od infront of an amp). It wasn't massivly drastic, and again haven't heard it through his half stack.

Only thing was that I had to "modify" the control drilling since the shaft was a bit bigger, and the standard knob barely fit on it.
