The reverb on my ezg-50 kicks in and out. I know usually when there is a failure, it just dies. But this issie has been ongoing for awhile. Sometimes no verb at all and sometimes perfect. Anyone have advice or experience? Thanks much. Jake

How old is the amp? I've never had a verb fail but my 1st look would be the cables coming in and going out of the tank. Spray a small amount of DeOxit (electrical contact cleaner) on the male ends and plug them in and out a few times - that will eliminate and oxidation that might be cutting your signal. As far as the reverb driver tube my guess is it either fails or works - I don't think it will be a sporadic issue, but it wouldn't hurt to spray the pins on that tube and do the same as the RCA plugs (plug in and remove a few times to remove any oxidation that may be there as well). After all that, if it still has issues it may be the reverb tank itself. I would try the other things before opening up the tank. I've never had a reverb tank fail, but you never know. Also, you could email or call the Z Shop directly and get some more qualified knowledge!
Let us know what you find out.

It is an older model, but it serviced and brought up to specs from the folks at Dr. Z. All that makes sense. I'll give this a shot and report back. Very much appreciate it!

Just logged in to ask what to do if the reverb stops working entirely when I found my own threat. Well, anyone have a suggestion? If the tank is bumped it definitely reverberates, but there is no actual verb coming through otherwise. I tweaked the wires a bit last week and managed to get it to come back in, but now it is gone. Thanks!

Thanks! Do you have a spare reverb driver tube to try (in the event the tube has failed)? However, if you had a wiring problem before it may still be similar to that.

Also, if you have an extra set of RCA cables you can try those as well.

All that makes good sense of course. I will grab a tube and some cables and go from there. Thank you!

Tried swapping tubes and a new set of cables. Neither had any effect. Will try the deoxit and see. Thanks!

Deoxit it didn’t do it either. Will try a few more things and then ship it off . . . . Thanks all!

Hi Jegersen. Welcome to the forum. Based on the original post, (ie: it works perfectly, then not at all) it sounds like the problem could be intermittent contact somewhere in the circuit.
Do you have a digital volt meter that tests for continuity ? If you're not going to use it much, get a cheap one for less than 10 bucks. Wiggle the tank and the cables while holding the probes to the TIPS of the connectors coming from the tank. See if you can replicate the problem. If you have good continuity, then you know the problem is somewhere in the chassis.
Good luck, hope you find the problem.

Could also be a broken connection in the tank itself. One of the springs could have detached or broken at the ends. Not an expensive or difficult repair, literally plug and play.

Turned out to be a broken connection inside the tank. Obvious once I got it open. All set now. Thanks to everyone for the suggestions. Really appreciate it.

Glad you got it worked out. The verb on the EZG is among the finest in existence.
