I have just recieved my ET65 and installed it this morning in my Rivera Clubster ROyale amplifier.
It sounds good even without breaking in, but amp hum got louder.
What can I do about it? Why would it happen?
That might be called a 60 Hz Hum which happens do to bad wiring of a place. I don't know if it's a combo amp or a head but if you don't have anything that ground lifts then you can try and getting an adapter at home depot that takes 3 power connection adapter into 2. See if that solves the problem :)
I just put an ET65 in my solid state Peavey Studio Pro 112 and I now have more buzz too. I am sure the speaker model is just a coincidence, but I thought this was really odd. Last night I could sit right in front of my amp with either of two guitars, and it was almost dead silent. Now, since putting in the new speaker, I can hear a buzz/hum that goes away when I touch metal or strings on the guitars. Also for some reason, I get less hum when I switch to the bridge pickup by itself... really weird, I think. One guitar has three DiMarzio rail humbuckers, the other has two G&L ASAT single coils. Is the speaker itself really adding that much noise from being more efficient?
After a lot of experimenting, I have decided the buzz I am hearing must have more to do with my environment (apartment wiring, etc.) and guitars. Perhaps I am hearing certain frequencies a lot better than I used to with the stock Blue Marvel. I think that's why the noise jumped out at me after the speaker upgrade.
"Perhaps I am hearing certain frequencies a lot better than I used to with the stock Blue Marvel. I think that's why the noise jumped out at me after the speaker upgrade." Yeah, that would be the most common explanation!
Connect a wire from the metal speaker frame to the amp chassis. (ground the speaker frame) This should stop the HUM. You can connect the wire to the speaker mount nuts...
What is actually happening is: The speaker magnet voice coil is picking up the magnetic field of the power transformer. This happens when you install a good (beefy) speaker... But grounding the speaker metal frame usually cures the hum.
Other than the ET having a lot of bottom end, and possibly being a bit more efficient (louder) ... I can't think of any way a speaker can cause "hum".
