The reverb knob on my Blues Jr. has no effect. Is there something I should be troubleshooting before hauling in to the amp tech?

Thanks,
Dwayne

Here is a great page all about Blues Jr's, down on the left is an article about fixing the Reverb tank. Perhaps this will be helpful to you.

I've heard of a couple that have had reverb problems and also the phase inverter is prone to oscillation. Although not all that common. If you happen to start hearing a kind of a funny ringing sound. It would first have you think it was bad tube or a speaker. It may well be a phase inverter.

Here's another site with good information. Mhuss.com
