I bought a 112 RP 100 watt a couple of months ago. My first MM and I'm really excited. It sounds beautiful except for one thing: when I play low sustaining notes really loudly, there is a buzz. (Both with and without the deep setting; more so with it on.) Volume 10, Gain at about 6. I can't find the source of the buzzing. Here's what I've done: 1. Tightened all the screws around the speaker (not too tight, but snug). 2. Tightened all the screws around the cabinet, inside and out. 3. Took it to an amp tech who (because of intense white noise) did the following: a) replaced chips b) replaced caps c) replaced and biased tubes He said that when he plugged it into another cabinet it didn't buzz. So he recommended getting a new speaker, assuming the old black widow peavy was rubbing. 4. So I bought a new Eminence Texas heat -- not the greatest speaker but brand new and decent. 5. Moved all the wires inside the cabinet to the side so that they wouldn't touch the speakers. The buzzing has lessened, but it is still there. The closest I've come to finding it is by playing a low sustaining note and pushing my thumbs (through screen) against the bottom two screws with protrude from the backside, bottom part of the speaker. But I still can't nail it down. Now that I've explained everything I've tried, I'm wondering if there's anyone who can help me find a solution. Added note: My wife says she can't hear the buzzing from the other room in the apartment, but I don't know how it's going to act up in the club we're supposed to play at. One more note, the amp isn't blowing my head off at this volume (Volume 10; Gain 6 or 7), but I'm not strumming super hard, I'm plucking at the strings. It's loud, but it's not blowing my face off. Any thoughts? Thanks, Doug | ||

Sorry, didn't see this. Not much help other than you can isolate cabinet squeeks by taking the baffle board out and rubbing a plain bar of soap on the mating surfaces, put it back together and see what it sounds like. It just sounds like cab squeek to me. UNLESS, you have a glue joint coming loose. THAT is a a pain. That requires taking the acb apart and re-glueing, or at least trying to force glue down in the joint. I'd try the baffle board soap thing first, to rule it out. Volume, that should be cranking but not know what guitar you put through it makes it difficult. Single coils have very little output while humbucks would drive the front end pretty hard. Let me know if I can be of any help. Mike. |
