Munurmunuh Posted January 15, 2022 Share Posted January 15, 2022 My Squier P came fitted with ki0gon loom, which I believe means 250k pots and a 047uF cap. I had a Dimarzio Model P pickup fitted. Dimarzio suggest a 500k for the Vol, 250k for the Tone and a 033uF cap. If I swapped the Vol and/or the cap over to Dimarzio's suggestion, what differences would I hear? For what it's worth, I keep the Vol on 10 all the time, occasionally take the Tone down to 7, and only use rounds (changed more often than really necessary ) Quote Link to comment Share on other sites More sharing options...
Thunderbird Posted January 15, 2022 Share Posted January 15, 2022 I would leave as is to be honest 500k pots will just make it a tad brighter not used a 33 cap but would not think it would make much difference 1 Quote Link to comment Share on other sites More sharing options...
Munurmunuh Posted January 15, 2022 Author Share Posted January 15, 2022 I'm ignorant enough to be deserving of a much more patronising answer than that. Brighter all the time? Or simply less darkening when turning the tone? I'm about to change from Fender nickel-plated strings to Pro Steels, which I'm expecting to make a big difference to the brightness, amongst other things. Relative to that, would a change of pot and/or cap make only a minor difference? I'm going to be interested to see what's left of the Pro Steels tonal balance when the tone knob is turned right down. ATM, I don't find that setting much use. Quote Link to comment Share on other sites More sharing options...
itu Posted January 15, 2022 Share Posted January 15, 2022 The change of pots will be minor compared to the change of a new set of strings. Leave it that way. 2 Quote Link to comment Share on other sites More sharing options...
Munurmunuh Posted January 16, 2022 Author Share Posted January 16, 2022 I found this explanation of the cap: When you put a 0.047µF cap on a 250k pot, it will make a low-pass filter with a "knee" right around 300Hz. Take that same circuit and throw on a 0.022µF cap on there, and the cutoff frequency moves to approximately 850Hz (give or take a few). When you turn the Tone knob down, you are lowering the volume of all frequencies above that cutoff. I can now understand why Dimarzio recommend a lower value than .047 for the Model P. I think I would find the tone control more useful if I changed mine. And I found this comment on pots: The 250 kohm pots will load a little more to ground, making the circuit have a tad lower resonant peak, and therefore a more even tone across the spectrum, a little "warmer" overall. The 500 kohm pots will load less to ground, so that the resonant peak is a little higher, a little brighter tone. But on bass it is so subtle, that a slight bump of the tone knob will do more than the value of the pots will. Quote Link to comment Share on other sites More sharing options...
Munurmunuh Posted January 16, 2022 Author Share Posted January 16, 2022 @Bassassin Since this Matt Freeman of mine is an Ibanez Blazer wannabe, I can't resist asking you what pots and cap are in them Quote Link to comment Share on other sites More sharing options...

Munurmunuh Posted January 17, 2022 Author Share Posted January 17, 2022 Bass has to visit the tech for a couple of other things, so I'm having the .047 cap swapped for a .022. If I don't like the tone knob's effect any better, then no loss Quote Link to comment Share on other sites More sharing options...

Instead of turning the bass into a mud machine, the knob now just gently takes off the gleam, leaving the meat of the tone in place – exactly what I hoped for Quote Link to comment Share on other sites More sharing options...
bloke_zero Posted January 20, 2022 Share Posted January 20, 2022 Nice, I've experimented with going .06 and that was very different - didn't make it muddy because the peak or bump is at the cutoff point so accentuated the mids, but it really cut into the tone making it very dubby and woody feeling. 1 Quote Link to comment Share on other sites More sharing options...
