hey, im trying to hook up an amp to my home surround sound, it has up to 180W going to the sub and i have spliced into that to make a (pre-amp) for my new 3000w (350Wx2ch) amp but i dont want to fry the inputs with the 180w input, so im trying to install a "pot" to turn down the input into the new amp. im wandering if there is a formula to tell me how many ohm pot i need to splice in? any clue?? i dont even know it this will work. any hints?
Dude I have a question.I have a Fender P-Bass with Active 3 Band Preamp.I get alot of mud.Its got a Double Jazz at the bridge which isnt mid focused. I checked the pots & they are all 100k pots.The bass has Passive pickups.
Should the Pots be 100k ? If i change the value of the eq pots could it improve the sound ? Also when blend is in the middle it sounds as if it sucks whatever mids are present. The blend also has a Scratchy thing going on.I can feel it when i turn it .HELP !!
Thanks for the upload - I can now find out what pots are in my 1991 Gibson Explorer (Gibson say they don't know as they used both 300s and 500s that year!)
Thanks a lot for the video but I don't understand why my 500k pots measure 522k (B volume) and 449k ( A tone), just like your 500k CTS pot measures 537k. Does this mean they are broken or not working correctly?
@Nicolauru - Pots will vary what they actually read just like many other electrical components. They are made to certain tolerances like 10% or 20% so a 500K pot can range from 450K-550K the one I show in the video is actually a 10% CTS500K and they are actually built to 550K specs so that is why it reads around 536K With humbuckers you actually want your volume pots to read over 500K that way you get more clarity and less muddiness. I meter all my pots before I use them in my wiring harnesses.
awesome video.. I'm Italian but you are very clear..... thnx my friend

Than ks for showing this! The only thing Im wondering is this, if you back it down all the way and still get a reading above 0 is the pot bad?

So when you turn the pot all the way clockwise there would be zero resistence right?
