Since a few weeks I have a really bad crakling treebly mixed with any sound from any overdrive I use, as if my speaker was dead (but it's not). Clean chanel sounds really ok. If I put a TS9 or other OD, I have a weird crackling sound mixed with the OD... Same sing if I use the Drive chanel of the RV50...
I've posted a VDO here (it's not my cam saturating) :

And another vdo i've made because at first i thought it was an problem with the OD so i wrote to the builder MaxZ :

(please forgive my bad english...
)Solutions I have tried :
- Changing power tube for new one --> bad sound still here.
- Changing all preamp tubes --> bad sound still here.
- Use another cab PPC212 --> bad sound still here.
Maybe it could be a too hot bias no ?
Thanks for you comment and help
