In parts 3 and 4 of this video series on tone capacitors, I answer some questions and record some more examples. I talk about 50s versus modern wiring, my recording setup and how the audio is processed, measured cap values, and how to do double-blind testing. In part 4, I record another set of examples, now including ceramic caps and distorted examples.
The caps I try here are: Orange Drop 225P 100V (polypropylene), Mallory 150 series (metallized polyester film), Russian K-409 PIO (paper in oil), mystery vintage yellow cylinder (identified as WMF 1S22 Polyester Film 100v from CDE Cornell Dubilier), the original Epi tone cap from my Riviera (probably mylar polyester film), NTE ceramic, mystery vintage gray cylinder (identified as Mullard/Phillips Mustard polyester foil/film 630v), and a vintage tropical fish (polyester film).
Correction: at 3:34, I misspoke- the cutoff frequency doesn't actually change. Just the amount of signal passed through the cap. On 10, very little signal passes through the cap to ground.
Everything is played on my Epiphone Riviera P93 with Vintage Vibe Guitars P-90 pickups, through my Vox VT30 on the Boutique Clean and AC50CP2 models, mic'd with a Rode NT1 large diaphragm microphone.
