i play through a late seventies 135 RMS fender twin that i bought about eight months ago. often when i attack the strings too hard or hit certain high notes, i get a weird feedback-like tweet with a bunch of noise. this is especially noticeable when i use reverb, but now i hear it in the clean channel too. might the tubes be burned out or something? what's goin' on?

If you never changed your tubes then its probably the tubes.
