I have a 15watt Fender Pro Junior amp. The sound has become more distorted and there like a harmonizing effect occurring when I play single overdriven notes. I replaced the pre amp valve with new ones but the problem is still there any ideas, is it worth replacing the power valves. They were replaced 18mths ago but I do play a lot of gigs approx 300 a year ?

Try replace output tubes. It look you play lots of hours.

Pro junior need a bias check by a tech if you want the better of your tubes and amp.
Tubes last longer with proper bias . You must see a tech for that.
Be sure to see a good one , not anybody on music store.......
