unclej Posted August 18, 2004 Report Posted August 18, 2004 my current project is going to have a dimarzio paf in the neck and bridge position (joe and fred) with a virtual vintage blues in the middle position. i understand that the early les pauls had 300k pots with their pafs and that was one of the reasons for their unique sound. any of you have any practical experience with them and if so, can you describe the difference between the 300k and 500k sound?

lovekraft Posted August 18, 2004 Report Posted August 18, 2004 The lower resistance pots cause greater high-end loss and lower output, making the sound either "warmer" or "duller", depending on your point of reference. It's kinda like having the tone pot cracked open a bit on a 500K setup, just a bit of treble cut. Quote
unclej Posted August 18, 2004 Author Report Posted August 18, 2004 thanks for the response lovekraft. the fellow at allparts said, "it makes the high end a little smoother" and i assumed what you said is what he meant...i think. Quote
ansil Posted August 19, 2004 Report Posted August 19, 2004 you can mimick this, pretty easy. change the tone pots cap to a 1mfd. i know this sounds extreme but it has a certain sound to it that isn't completely muddy. just roll it down from 10 to 7 and play with it. a wicked little sound. Quote
unclej Posted August 19, 2004 Author Report Posted August 19, 2004 thanks ansil..did you really mean a 1mfd or a .01? Quote
ansil Posted August 20, 2004 Report Posted August 20, 2004 thanks ansil..did you really mean a 1mfd or a .01? yes i meant a 1mfd.. i know it sounds weird but it shifts the whole tone range so that it eats up a bit of the highs but also takes down some of the gain. its a matter of playing with it. i used it on most of my guitars for years.

unclej Posted August 20, 2004 Author Report Posted August 20, 2004 well i'm definitely going to have to try that just to hear what it sounds like. thanks again. Quote
AlGeeEater Posted August 23, 2004 Report Posted August 23, 2004 is a 1mfd cap the same as 100pf? Quote
ansil Posted August 23, 2004 Report Posted August 23, 2004 1mfd=1uf or 1,000,000pf radioshack part no. (my personal favorites cause they are so inacutrate. i guess) 272-1055 http://www.radioshack.com/product.asp?cata...t%5Fid=272-1055 Quote
AlGeeEater Posted August 24, 2004 Report Posted August 24, 2004 I just went to radio shak now and got some Quote
AlGeeEater Posted September 2, 2004 Report Posted September 2, 2004 I put it in and wen i roll down the tone knobs towards one(both of them) i can barely hear anything. and wen i turn them all the way off it acts like a volume knob and turns off the sound. Is that normal? Quote
ansil Posted September 2, 2004 Report Posted September 2, 2004 how did you wire it.??? it does have a great rolloff and at max resistance it will limit quite a bit of signal thats why i never turn it more than say33% down. but i also use a 1M or 500k pot too.. Quote
litchfield Posted September 2, 2004 Report Posted September 2, 2004 You can also use a 200k resistor on a 500k pot, modifying the tut on the main site. Quote
AlGeeEater Posted September 2, 2004 Report Posted September 2, 2004 (edited) Well its a strat setup guitar and um 250k pots. I wired it just like it was wen i removed the stock cap. You can also use a 200k resistor on a 500k pot, modifying the tut on the main site. What about for 250k. i couldnt do the math Edited September 2, 2004 by AlGeeEater Quote
lovekraft Posted September 2, 2004 Report Posted September 2, 2004 You can also use a 200k resistor on a 500k pot, modifying the tut on the main site. Wouldn't that give you about 142K? As I remember, the result is always lower than the smallest of the parallel resistances. Wouldn't it take a 750K in parallel with the 500K pot to get 300K? Quote
litchfield Posted September 2, 2004 Report Posted September 2, 2004 Possibly, I know the concept, but not the procedure, hence I reccomended reading the tut. Quote
AlGeeEater Posted September 2, 2004 Report Posted September 2, 2004 You can also use a 200k resistor on a 500k pot, modifying the tut on the main site. Wouldn't that give you about 142K? As I remember, the result is always lower than the smallest of the parallel resistances. Wouldn't it take a 750K in parallel with the 500K pot to get 300K? No, the 750k alone with the 500k pot would read 300k. i just checked the tut. Quote
lovekraft Posted September 3, 2004 Report Posted September 3, 2004 No, the 750k alone with the 500k pot would read 300k. i just checked the tut. No offense, but isn't that exactly what I just got through saying? ...Wouldn't it take a 750K in parallel with the 500K pot to get 300K?... For anybody who's interested in the math, the formula for parallel resistances is 1/Rtotal = 1/R1 + 1/R2...+ 1/Rn, ie, the reciprocal of the total resistance is equal to the sum of the reciprocals of the parallel resistances.

unclej Posted September 3, 2004 Author Report Posted September 3, 2004 hmmnn...do the math or let you guys do it..man, that's a tough one. i finally got all of the parts in for the project that led to this thread including the 300k pots so when i get it put together i'll let you know how it sounds.

AlGeeEater Posted September 3, 2004 Report Posted September 3, 2004 (edited) No, the 750k alone with the 500k pot would read 300k. i just checked the tut. No offense, but isn't that exactly what I just got through saying? Nooo not in a parallel. Just the 750 with the 500 would make 300. You said in a parallel Edited September 3, 2004 by AlGeeEater Quote
lovekraft Posted September 3, 2004 Report Posted September 3, 2004 But they are in parallel! They have to be wired either in parallel or in series, there are no other options. Perhaps you're confused by my use of electronics jargon. Quote
