Mysterious Buzzing Ampeg

Just an interesting tidbit.

Almost every town of any size has the local music store. Not the Guitar Center, but the old guy that has been around since dirt was invented and has stacks and stacks of old amps, instruments, balogna sandwiches etc. So we have one in our town. I like the owner and go in there often to visit or particuarly when I have a bad case of GAS and want to trade six or seven of what I have for one of something he has. (You know, buy high sell low - trade ridiculously)

So I'm amp shopping and go in and in the back of one of the rooms, under everything else is an Ampeg Reverb Rocket. I have always liked Ampeg amps for some reason and here is this 50Watt tube amp with 2 12" and it looks almost like new. So we do a trade and I take it home, only to find out that with any bass notes it buzzes a lot. One of those annoying buzzes that you can't quite determine if it is from the amp, a too low string on the guitar, or the stuff sitting on a shelf in the next room. Try as I could I couldn't determine the source of the buzz. I took the amp apart and tightened every thing up to no avail.

So we take it back and try it in the store and it doen't buzz. Take it back home and it does buzz. About this time I noticed that the leather handle had enough wear under it that some of the thread that sews it together was beginning to wear a little too much to look new and I ordered a new handle. ( So much for it being unused).

The new handle gets there and I unscrew the bolts holding the handle on and notice that on one of them there is nothing to unscrew, the bolt just comes out of the top of the case.

After this I decided to open it up and tighten all the screw again,  fastneers bolts etc on the whole rig and took the back off only to find that one of the tee nuts that had held one of the bolts on the handle was missing.

About an hour of searching around with a flashlight and a small shop mirror revealed the tee nut had come off the handle, fallen straight down through an opening in the speaker and attached itsself to the inside of the the back of the speaker by magnetic force.

Once removed and returned to it's rightful place holding one of the bolt handles in place, the buzz was gone and I was rewarded with a fairly new looking Ampeg 2 x 12" tube amp that sounds great once again.

Watch for falling nuts!

Ron, I also have a '61 reissue Reverberocket -- 50W, single 12", with the blue diamond Tolex. It is a sweetheart. I don't gig with it anymore, but I'll never get rid of it. Too many lessons learned the hard way. Hang on to it.1997 Nitefly SA

Had to choose between a Reverberocket and a Fender HRDx a few years ago.
The Fender has been fine but the Ampeg would have been a better choice.
Glad you figured out the problem.
