A 250k pot (full on) with a .0015uF puts the knee @ 400Hz with a 3dB/octave roll off. A 125k pot, (R/2) the knee is @ 850Hz more or less with 3dB/octave roll off which makes perfect sense. (half the R = 2x the freq.) This is going to make me rethink ALL the caps in my Strats. Given that they are all quacky with no warmth... Damn it all 🥴 'The proof is in the pudding', as they say, real world results tell all the story that needs be told, for the most part. It might save you some math-work and maybe some of the trial-and-error to peruse the following from the Lindy Fralin pickup site: "Fralin Magic Cap: Lindy’s favorite cap to boost the midrange of a shrill single-coil pickup. This value is extremely subtle and tends to work on bright pickups only. .0022: Great for bridge pickups and bright sounding guitars, this cap will boost your midrange and tame a few of your high frequencies. It’s a little stronger tone than our Magic Cap. .02mfd: This popular cap is very usable throughout the entire pickup line, and works well on Humbuckers and Single Coil pickups. Gibson and Fender use this cap as a standard for more modern guitars. .05 / .047mfd: This popular cap works well with Humbuckers and Single Coils and goes pretty deep into the upper midrange. Use this cap if you want a warmer jazz tone from your pickups. You’ll see this cap used on vintage Fender Telecasters and Strats frequently. 1mfd: This cap will provide the deepest roll-off available. You will find this value in vintage instruments. The roll-off of high frequencies will start quicker and go deeper into the midrange than the other capacitors offered. - Lindy Fralin Quote Ask yourself- What Would Ren and Stimpy Do? ~ Caevan James-Michael Miller-O'Shite ~ _ ___ _ Leprechaun, Esquire _ ___ _ Link to comment Share on other sites More sharing options...

These are my go to caps for the reasons stated. .02uF is my preferred because I tend towards single coils (with exceptions). I'm probably wrong, but I think the use of the .047uF is due to the 500M pot used for humbuckers. 2 Quote What? Link to comment Share on other sites More sharing options...
