Hello, i need some help please!

Yesterday i was playing my 1966 blackface when i realize that the vibrato channel start sounding very thin in bass, mids and everytging, like i were using the bridge pickup of my stratocaster(i was using the neck one). Then i plug the cable into the normal channel and everything was ok. I already put new power and preamp tubes so i know tubes are not the problem.
Does anybody knows what could be the problem? Thanks

Also when the amp start to sound thin i realize the bass and middle knob does not work! till it fix alone and then both knobs start to work again.

try checking for cold solder joints along the tone controls. that may be part of the reason the controls arent working as well.

Today i am going to check that because when signal turns thin i realize that bass and middle knobs are not working!

Thank you!
