need help identifying caps

[blanik]

those are all 0.01uF caps that i have, they're so different from one another that i never know wich one to use!
i know that a cap that is not in the audio path shouldn't influence the sound but when they're used to shape the sound, wich one should i use??

(D has a glass casing, doesn't show well on pic)
(B they kinda look like ceramics but i don't think they are...)

i like using the smallest ones for my builds since they greatly improve the "boxability" of the board but i'm always worried that they'll sound bad (i know, irrational thinking that "bigger sounds better"  )

A = metal fim
B = Tantalum i think
C = Poly film
D & E =

with only rare exceptions, cap type is irrelevant IME.

[blanik]

B isn't tantalum, they look round but they're flat and not polarized... (lugs same lenght and no + sign...)

i often use E but i'm concerned that it can harm the audio path... (impression based on it's small size... )

b is ceramic, but those ceramic they use in telecommunications.  I cant remember the special name for it.

And for the record.  I made two Professor tweed pedals.  One with all ceramic, and one with all metal film.

I think the ceramic one sounds better.

E is also ceramic but axial, same as B

Monolithic!  Monolithic ceramic.

Right?

[blanik]

i often read here that people change ceramic caps for poly or metal cause ceramic adds some noise? probably talking about the old round ceramic cap...?

[tiges_ tendres]

I am too cheap to notice any noise!   

Personally, of the two prof tweeds I built, I think the ceramic sounds a little looser, a little more fun.  Like a drunk, older, cooler cousin at a family function.

Monolithic!  Monolithic ceramic.

Right?

hmmm
look at the first to pictures

checking ambulancevoice's link i just discovered that i bought a bunch of "bullet tantalums" 1uF caps 



i was trying to avoid those (i read here that they're noisy...), they're quite small though... about the sisze of a resistor...

E also is monolythic ceramic. D may be also (basically a surface mount cap in a glass package what it looks like). B (mono.ceramic) and E you see in some Dunlop wahs (probably because those caps are very inexpensive).

[blanik]

any clues about how different they sound?
should i go for a specific one?

 I read on an audiophile page that film caps have a sound quality that's like scraping a plastic butter tub with a knife, while ceramic is more like dragging an earthenware pot across concrete...

At the time I thought that was insane, but, after trying all film and all ceramic in a BMP... it starts to make sense... sorta...

[Dai H.]

just try them out and listen. Sometimes there seems to be a difference, sometimes not. Sometimes better, sometimes worse, etc. I tried changing a couple monolithic ceramics in my Marshall SE100 for some of the same but temperature compensating NP0 types but put the originals back in since they sounded more correct to me.

A=metallized polyfilm  B=Epoxy dipped ceramic  C=Mylar  D=polystyrene  E=Axial dipped ceramic

D is not a polystryrene. I have one of those in a Dunlop wah and a couple of 470pF like that. If the poster can provide a closeup you'll see what I'm saying above.
