My amp is creating an echo/reverb effect all on its own and it is neither equiped with reverb nor does it stop when i remove my reverb pedal from the chain. How do i get it to stop?
Turn it off? Unplug it? Burn it with fire?

More seriously, what amp(make and model) is it?

Try a new tube. Just pick up a JJ12AX7 (ECC83) and swap it. $10, takes 30 seconds.
