    I disagree. Lowering cap value make my guitar brighter. I did a little experiment last nignt to confirm this. Very noticeable difference. It's like changing pot value from 500k to 550k.
    Capacitor type/material, on the other hand, has very subtle effect, but it does affect tone.*
    I find those russian K40Y PIO sounds really muddy in the low mids. But who knows, perhaps I have a defective unit or something, because it seems to cut a bit of output as well.
    In my paul I currently use 0.022 orange drop 225p for the bridge (more woody, not as harsh as typical 715/716 orange drop).
    And silver mica 7500pf for the neck. The neck pickup is muddy and lifeless (gonna change soon) so it needs extra dose of brightness and clarity.

    No. The tone is the same if the value of the resistor is the same. The amount of noise increases with carbon comp, but the frequency response is EXACTLY the same if the value is exactly the same. It's math.

    I've decided not to allow myself to care too much. I simply don't have the time. I envy those of you that do. Honestly.

    Took this advice and since I have a boatload of old Sprague 157P tan, decided to try one in the LP neck position.
    Stephens Design PAF Star prototype.
    Big difference, same value (.021uf) but much clearer in tone.
    Not sure what the 157p is, but I'm sure it's not PIO.
    Mylar or poly?

    Not my pic, but these are the same:

    Maybe a bit late here buy here's my take on pio caps. I have been playing professionally for 50 years, played about everything with just about everybody. My love for the Les Paul started in the mid sixties and I own quite a few as well as a rather large arsenal of other guitars. Every LP I own or will own gets PIO caps sometimes two .022s sometimes an .015 at the neck. For the last 50 years I have done this religeously, there is reason for it. Tone. P.S. Jonesey the matched set of .015 and .022 Hyrels I got off ya on the bay sound incredible in my 60 LP!

    Hi everyone,

    I just wasted about a half a day reading through this thread, but then again i didnt have anything better to do and it was informative.

    I especially liked the part where it was discussed if capacitor value changes brightness. It was kind of like buying a dimmer switch for your bedroom lighting and buying a lightbulbwith lower wattage because you want to make it darker when you dim it all the way down to 0. I failed to see the sense in changing the capacitor value to a lower number to make your guitar brighter on 10.

    There might be a difference, but you get that thoretical difference as a bonus anyway if you go to a lower number capacitor to make your guitar less dark at 1.

    What I wanted to know is, whats the history on the 400v Cornell Dubilier Green PIO caps. Has anyone here had experience with them enough to know if they are worth the price. (Going for about 15 bucks a piece). Were they ever used by Gibson?
