so while my fender deville is in need of a retube its making this weird rain on a tin roof windy sound when i turn my volume down and drops in a out whenever the hell it wants


any clues as to why its doing this

[metalmariachi]

Resisters on the preamp tube plates can cause this.

plate load resistors possibly kaput?

[metalmariachi]

Yup, all those neat but unwanted sounds, popcorn, babbling brooks, bacon are usually the plate load resisters.

If some one made a pedal that did that you’d want it LOL.
