so the cmoybb bom calls for:
 
 
[size=8pt] CB_L, CB_R[/size][size=8pt] WIMA 0.068uF Polyester Film Capacitor, 63V, 5%[/size][size=9.5pt] [size=8pt]505-MKS20.068/63/5[/size][/size][size=8pt]  [/size][size=10pt] $0.25[/size][size=10pt] 2[/size][size=10pt] $0.50[/size]
[size=8pt]    CB_L, CB_R[/size][size=8pt] Kemet 0.082uF Polyester Film Capacitor, 63V, 5% 10%[/size][size=9.5pt] [size=8pt]80-MMK5823M63J01L4[/size][/size][size=10pt]  [/size][size=10pt] $0.22[/size][size=10pt] 0[/size][size=10pt]  [/size]
[size=8pt]    CB_L, CR_R[/size][size=8pt] WIMA 0.1uF Polyester Film Capacitor, 63V, 5%[/size][size=9.5pt] [size=8pt]505-MKS2.1/63/5[/size][/size][size=8pt]  [/size][size=10pt] $0.25[/size][size=10pt] 0[/size][size=10pt]  [/size]
[size=8pt]    CB_L, CB_R[/size][size=8pt] Panasonic 0.082uF Polyester Film Capacitor, 50V, 5% 10%[/size][size=9.5pt] [size=8pt]667-ECQ-V1H823JL[/size][/size][size=10pt]  [/size][size=10pt] $0.29[/size][size=10pt] 0[/size][size=10pt]  [/size]
[size=8pt]    CB_L, CR_R[/size][size=8pt] CDE Polyester Film Capacitor, 50V, 5%[/size][size=9.5pt] [size=8pt]598-DSF050J823[/size][/size][size=8pt]  [/size][size=10pt] $0.76[/size][size=10pt] 0[/size][size=10pt]  [/size]
 
I have:
 

[size=small]CAP .1UF 50V 10% CER RADIAL[size=small]http://parts.digikey.com/1/parts/64964-cap-1uf-50v-10-cer-radial-c320c104k5r5ta.html[/size][/size]

 





 I have:  1.0 UF 63v 5% vishay polyester film cap
http://www.mouser.com/ProductDetail/Vishay-BC-Components/BFC237012105/?qs=sGAEpiMZZMvOcEq4GH1AAnDObYAgO69msMALw4kx6Do%3D 1.0 
 

[size=small]CAP 1.0UF 63V METAL FILM BOX http://parts.digikey.com/1/parts/84099-cap-1-0uf-63v-metal-film-box-bfc237012105.html[/size]

 
I think the first part that I have Cap .1UF 50V 10% cer radial should work, so if that is the case, awesome. If it is indeed a go ahead and solder, I'd like to know the why. While I am asking questions what does CB stand for?

The 0.1uF Ceramic will sound awful.
Ceramics are for RF bypassing and should
never be used for audio.
Stick with the Polyester.
 
CB = Capacitor Bass

I am checking with the BOM for the CMOYBB and it specifically calls for 
[size=8pt] C3+, C3-, C4+, C4-[/size][size=8pt] 0.1uF, 50V Multilayer Ceramic Capacitor[/size]
 
for the above. Kind of strange why they are asking for ceramic after understanding the inherent problems with them. Thanks.

They are being used correctly for RF bypassing in that position.
