Hosco Paper in Oil Capacitor Cylinder - .022uF

Hosco Paper in Oil Capacitor Cylinder - .022uF

Paper in Oil Capacitors are great for guitar players who want vintage-era tones in their guitar. Made to exacting standards in Japan, this cylinder-type capacitor requires slightly more room than the slim type.

What is Paper-in-Oil?

Paper in Oil (PIO) capacitors are an older technology, highly sought after primarily due to their use in many vintage instruments such as 50s era Gibsons. The capacitor is literally filled with paper and a special oil before being sealed in thermoplastic. The thinking behind PIO construction was that it improved cooling and improved insulation, which was necessary at the time due the high voltages involved from audio amplifiers that were vacuum-tube based.

Paper in Oil Caps

PIO capacitors deliver a darker, warmer and smoother tone, which is why they are so sought after for those seeking a more vintage aesthetic. The famous Black Beauty and Bumblebee capacitors were used in vintage instruments and guitarists have been seeking these capacitors in their search for tone for some time now. It makes sense that you would use an older technology to get the tone you want, if you’re going to the trouble of installing period correct pickups, body material, paints and machine heads, why stop at the capacitors you use?

Despite being an older technology, Paper in Oil Capacitors deliver high quality tone that's great for classic guitars, or for a modern build with a vintage aesthetic. This .022uF value is great for humbucker equipped guitars.
