# What cap is this?

It is branded "DME 250V
CD 104K" in a Dingwall ABI. I am trying to find a way to get more hi-mids without installing a preamp.

Thanks, Bob

I would guess it is a 0.1 uF, 250 volt capacitor.
I'm also guessing it is shaped like a disc. If so, it is a ceramic capacitor.

The value comes from the 104K. The '4' is an exponent (number of zeroes).
So, it becomes 10 x 10^4 = 100,000 pF = 0.1 uF.

Thanks for the explain. It's a squarish disc. What I am trying to acomplish is a more pronounced hi-mid tone. My Dingwall has the perfect tone with a pick, but my finger tone is lacking something. I have a 333K orange drop here, but what values should I experiment with?

tone with a pick is bright, finger plucking lacks the bright edge...so I'm guessing that if you're digging your pickin' but not your fingerin' then your cap is too big...

what's a 333k? would that be a 0.33uF??? if so...that's probably gonna deliver some real mud in the fingerstyle department...go with a 0.1uF or a 0.047uF...

OPEN IT UP

So, the higher the value, the better treble you get. 0.1 better treble than .033? or are you saying .333 is higher then 0.1

6. ### warnergt

333k is 33 x 10^3 = 33,000 pf = 0.033 uF.

7. ### RockbobmelSupporting Member

If 0.1 (Existing cap) is a higher value than 0.033, I am getting better treble now than if I swapped it out?

8. ### PilbaraBass

a capacitor that is shunted (as in a passive tone control) will let more highs get to your signal chain if the value is lower...

think of caps as a short at high frequency and an open circuit at lower frequency (DC)...so when the value is higher, it provides more "shorting" at frequency than a lower value cap...

in short, the 0.033 will give you better treble than the 0.1
