New Mod Reverb GREAT...but, only lasted 2 minutes....HELP

George Kimery · From: Limestone, TN, USA

I replaced the stock acutronics reverb in my 112 with the Mod 9EB2C1B reverb as Tommy White suggested. It was a big improvement over the stock acutronics reverb. I was really happy, for about 2 or 3 minutes, then it went dead. I have a replacement coming in. Was it just a bad unit or what? I was careful to plug the RCA plugs the same way as the reverb that I removed. Is there anything that I could have done wrong? Is there anything that I should check or have checked before installing the 2nd one that is on it's way? I don't want to repeat history.

Thanks for any help or ideas.

If, while it was working, it sounded good with no hums or buzzes, I'd say it was a defective unit that just died an early death. Could have been one of the very fine wires that lost it's connection. I would expect the next one to work just fine, George.

You might check with a voltmeter before connecting the replacement... if there's DC voltage coming out of the drive connector that would explain why the tank only lasted a few minutes. You might also do some checking on the other tank and see whether the drive circuit or the recovery circuit opened up... again, use a meter, this time set to ohms, to determine if one side opened up, and if so, which side it was. Good luck.

Mike and Stephen, thanks for your replies. Stephen, I can check if there is DC current coming out of the leads from the amp, no problem. But I am not sure how to check ohms on the tank. Should I check the RCA jacks on the tank? One probe on a plus side and one on a minus side, on the other side of the tank? Or check plus to plus and minus to minus? I just am not electronic savy enough to know where to put the probes to check ohms on the tank. And what sort of readout should I get to show that there is a problem or if everything is normal?

I just happened to remember something, that may have a bearing. The original reverb unit went out a few months after I got the amp. However, I got it used and the previous owner didn't have a problem with it. I had an old session 500 here, so I took the reverb out of it and put it in the 112. It has never given me any problem. Also, the amp has the Ken Fox chip mod. Any of this relevant?

Thanks,

George

George, using the phone here, so no long-winded diatribe right now. Yes, just ohm the RCA jacks... there's a coil on the inside of each one, one should be low ohms and
The other should be higher ohms.

Let me explain my set up at the time and what I was doing, just to cover all the bases. I had a Lil Izzy out of the guitar to a Goodrich 120 volume pedal, then out of the volume pedal to a Wet Reverb pedal then to the amp input. I was comparing the sound of the Wet Reverb to the mod reverb unit. I was experimenting with a "blend", some Wet Reverb and some amp (mod) reverb at the time it went out. I wouldn't think the Wet Reverb would have been the problem, but I guess anything is possible.

2 minutes? You must have gotten the deluxe model.

Everything is OK now. After the Mod reverb wasn't working, I sent it back and just got a new one in today that works fine....BUT......after I sent the first one back, I decided to hook up my old reverb, just for the heck of it. It didn' t work either, although it had been working fine. On closer inspection, I found ground wires on the RCA plugs torn loose. Both RCA plugs looked pretty bad. So I replaced them with new plugs and everything is working great. I called Antique Electronic Supply and let them know that the unit I shipped back may be OK after all.

Installation was a cinch, just unplug the two RCA plugs from one reverb and plug them into the other one. As Tommy White posted, the unit I got is P-RMOD-9EB2C1B. This is a substitute for the reverb that comes in the Nashville 112. This may or may not, be the correct unit for a different model amp. If you order one, get the model number of your old unit so they can cross reference what Mod unit will be a suitable replacement.

According to my ears and preference, here is my take on the Mod reverb unit:

Is it better than the factory reverb that came in the 112?

Absolutely. More lush sounding and more body. Not as thin and tinny. A definite improvement. This is probably the best sounding spring reverb that I have heard, except for some early Fender's. If you like spring reverb, and don't want to spend much money, this unit is worth looking into. Plus, it is much better made than the factory reverb..

Is it as good as my Wet Reverb pedal?

No, the Wet Reverb just sounds a lot more natural and smoother to my ears. But at $179.00 vs. $19.95, and digital vs. spring, one would expect a difference.

So, little has changed for me. I will still be using my Wet Reverb. The big plus, is I have a new, better sounding spring reverb that I can live with in the event my Wet Reverb develops a problem.

Service at Antique Electronic Parts, AKA as Amplified Parts, and Tubes and More. was fantastic. I live in NE TN and a LONG way from Tempe, AZ. I had them ship it the cheapest way. USPS Priority Mail. I had both units in 2 days and the shipping was $12.17. They shipped same day as the order was received. UPS would have been $5.00 more and would have taken 4 days ground. I have been having real good luck with the old USPS in the last several months, so maybe there is hope for them yet. I am through mean mouthing them for the present.

Your comparison doesn't surprise me; I'd prefer an outboard reverb over a solid state spring circuit. But my lexicon stays behind if I take the Twin
