Genz Benz NEOX 212T Buzzing
I have a Genz Benz NEOX 212T that has suddenly developed a very annoying buzz when I play.
It drove me crazy to isolate the problem. It's not the speakers or the grille, it's the tweeter attenuator. I've tried all sorts of ways to keep it from vibrating, which has helping a little, but not completely. The irony of this is, I hate tweeters in bass cabs! I don't use them, so I hate having to pay extra for components (tweeter and crossover) that I don't use.
I did send an email though the Genz Benz site about buying new parts, but since Fender bought up KMC, I hope the email doesn't go into a black hole.
IIRC, there is at least one person who was working at KMC who posts here. I'd really appreciate any help if my email goes nowhere.
Anyone else have this problem with a Genz Benz NEOX 212T cab?
I really like this cab. It cuts though a loud drummer, two guitarists, a keyboardist and vocals with plenty of low end and clarity.
Check a couple of things first. On the plate that the attenuator is connected to, make sure that there's not a bit of debris under the lip that might not allow it to sit down fully when installed. Also check to see that the wires are not touching the back of the attenuator and that the attenuator itself is tightened. There should be 2 nuts, the front and a backing nut. If the backing nut loosens up, it can vibrate.
Where are you located?
Thanks very much for replying!
I've made sure the wires were not vibrating against the attenuator. It is tightened to the rear plate. If I tap on the brass housing of the attenuator, I hear the same sound that resonates through the cab when I play.
I could disassemble it from the rear plate and check for debris.
I'm in So Cal.
It's also possible that the small clips that hold the back cover of the attenuator to the front structure loosened. If this doesn't solve the issue, I will look into other possible ways to solve this. It's not something that I have seen before so I can't give you a sure fire fix at this point.
Thanks again for your replies. After checking out the how secure the attenuator is to the back plate, I could find nothing loose or any debris. I did get a reply from my email to customer service, saying:
"These parts are actually distributed by KMC (Kaman Music Corp), any Genz-Benz dealer should be able to order these parts for you.
We are now selling parts and accessories direct! Call Today!
Fender Musical Instruments Corp.
Consumer Relations Dept."
Sounds somewhat contradictory to itself, but I'll give them a call. I can try, but I won't count on my local dealer to be of much help.
Worst case, I'll remove the attenuator and fill the hole in the plate with something else that fits and bypass the crossover and tweeter completely. I don't use the tweeter anyway. I'd just hate to do that in case I ever want to sell the cabinet.
