Ceramic vs paper in oil caps.
Pio caps were used in the les pauls of the 50 s and many appreciate their tonal qualities over more modern capacitors.
Paper in oil or pio caps are just one variety of capacitor.
The bumble bee caps were later replaced by the black beauties which contained a winding of aluminum foil and paper film along with oil and were printed with the specs.
I bought a bunch of vintage paper in oil caps.
Briefly a capacitor in the context of musical electronics consists of two plates of conducting metal separated by an insulating layer called a dielectric for example if you took two rolls of aluminum foil and unrolled them sandwiching a layer of paper between that would make a capacitor.
Truth be told i don t like one more than the other because i can t tell a difference.
Others are made out of mylar ceramic etc.
I m not saying i like the orange drop better than the pio.
A cap lets the tone control roll off the treble response progressively warming the tone.
The cheap ceramic caps are a little different story.
These caps were filled with paper in a special oil inside of bakelite bodies with the original nema color codes printed on them this is how many resistors are still printed.
