oli Posted June 1, 2005 Report Posted June 1, 2005 I am wiring a set of fender noiseless SSS pickups into a project strat and i am unsure of which capasitor i need for the tone pot some call for .022uf and some .05uf? the pickups came with a 681 1KV but they dont mention that on the diagram all i can find in the local electronics shop is an .022 -100volt and a .022 poly film cap 50wvdc this is my first wiring project and i want to get it right i hope this is clear enough Quote
Robert_the_damned Posted June 1, 2005 Report Posted June 1, 2005 its really up to personal choice rather than a set value. the larger the capacitor value the more of the high frequencies (and evetually mids as well) will be affected by the tone control. If your pickups came with a capacitor then that's probably the value the manufacturer thinks is right. but you can play arround and change then at will until you've found something that you like. hope that's some help!

thedoctor Posted June 1, 2005 Report Posted June 1, 2005 Actually, the Fender Noiseless (sic) sets call for a .022 and one should have come with them. Your better choice is to put in the Fender TBX tone control setup to try to get some shape out of these soldiers. The 50vdc is fine. A 5vdc does better for me but Radio Shack don't sell them. Quote
oli Posted June 2, 2005 Author Report Posted June 2, 2005 yup they came with a capasitor and a resistor but as i said the diagram that came with them makes no referance to them the capasitor is a 680pf and i think the resistor is a 220k the diagram however shows .022uf soldered to the tone pot so if i should use them i guess i have to find out how and where they get wired in Quote
Mr Alex Posted June 2, 2005 Report Posted June 2, 2005 the pickups came with a 681 1KV ← I cant tell you what value that is, but many capacitors have some other numbers on them, they dont always look like the value but they are usually a short hand method of writing it so values aren't confused(like writing 2m2 for a 2.2m resistor) Quote
oli Posted June 2, 2005 Author Report Posted June 2, 2005 i was doing some surfing while waiting for more input and found a site called all things guitar and they show the capasitor 681 iKV wired to the volume pot will i still need to install a cap on the tone pot also (TBX or 1Meg) if anyone is still with me here Quote

lovekraft Posted June 2, 2005 Report Posted June 2, 2005 Your pickups came with two capacitors - what you think is a 220K resistor is actually a .022 cap, and should be wired into the tone control as per the diagram you've got. The other cap (680pF) is your treble bleed cap, and should be wired between the hot side and the wiper (center terminal) of your volume pot (agian, follow the diagram). Quote

The other cap (680pF) is your treble bleed cap, and should be wired between the hot side and the wiper (center terminal) of your volume pot (agian, follow the diagram). ← I had though the same thing, but then remembered that many treble bleed circuits(well at least the ones I've seen) had resistors in them. i guess the capacitor is labelled 223.

lovekraft Posted June 2, 2005 Report Posted June 2, 2005 Absolutely, that's a .022uF cap - a standard resistor would have 4 or 5 color bands on it. Quote
lovekraft Posted June 3, 2005 Report Posted June 3, 2005 Boy, is my face red! I checked with my local Fender guy today, and he straightened me out. It turns out the set I installed wasn't the factory package, and the tone cap I was furnished with was a Radio Shack cap. The factory package we opened up does have a small cap and a resistor, both meant to be wired into the treble bleed bypass (in parallel). Sorry for the misinformation - I should check before I open my big yap! FWIW, the tone cap is available from Radio Shack: http://www.radioshack.com/product.asp?cata...5Fid=272%2D1066 I apologize for any inconvenience my stupidity may have caused. Quote
oli Posted June 3, 2005 Author Report Posted June 3, 2005 dont be so hard on your self thanks for giving it some thought i think we got what we need to get er done Quote
javacody Posted June 4, 2005 Report Posted June 4, 2005 Yep, that treble bleed circuit is one of many variations, some use just a cap, some use a cap and resistor in parallel, and some use a cap and resistor in series. Should have a tutorial on it. Quote
Paul Marossy Posted June 4, 2005 Report Posted June 4, 2005 What effect does the resistor in parallel with the cap have? Quote
Kyle Cavanaugh Posted June 4, 2005 Report Posted June 4, 2005 (edited) What effect does the resistor in parallel with the cap have? ← It let's some more of the lower frequencies through and lets the cap discharge quicker as it lowers the load resistance in parallel with the cap. I find just a cap by itself kills the harmonics kind of for me. Also, If you wired a cap and a resistor in parallel and ran it in series with a signal, it's called RC coupling, and I'm pretty sure it gives a rather pure signal except for a peak frequency that shifts in phase.

Paul Marossy Posted June 7, 2005 Report Posted June 7, 2005 Thanks for expounding on that Kyle. Quote
