I actually moved this to here from the Speakers and Cabs section because I'm not sure if it's the speaker or the amp, based on what I've been reading on other boards. My original post is below. Now I'm wondering if the amp itself is somehow generating a ghost note, as I've read that it is possible for an amp (and not the speaker) to generate these overtones. If it is in fact the amp, is this a cause that can be remedied? ----------- I have a Mazerati 1x12 combo with an Eminence Tonker in it. Haven't had the speaker that long, and there are probably about 20 hours on it. At a gig last night I noticed that I was getting a strange overtone with certain lower notes (a B on the low E string, if I recall). It sounds just like the artifical low octave you'd get when using one of those Boss Octave pedals (no, I don't have one on my board ). It kinda freaked me out, and I've never had an amp do that before. Is it the speaker doing that, or could it be something weird in the circuitry? I've heard the term "cone cry" used before in relation to speakers - is this what I'm getting?

I have a Mazerati combo as well, I have never experienced this with mine. If I were you I would send a PM to one of the administrators or use the "ask the experts forum.

Doesn't sound like "cone cry" that I would normally associate with certain Celestion models when pushed in the higher end of the spectrum.

It would be easy to verify whether it's speaker or amp by plugging in to an external cab and let fly. If you don't have another speaker cab, haul the amp in to the dealer and use one of theirs.

Wow - I just noticed the same thing recently. When I play a D on the low E string and partially mute it, I get that octave-sounding effect. I'm pretty sure it's not the amp - it did the same thing in the studio with a 2X12 cab in a separate room from the amp. The 2X12 has Eminence speakers too, so I'm wondering if this may be an Eminence quirk. When I get some time I'm going to try some speaker swapping to see if that is the case. It only seems to happen with that one note - very strange.

Maybe these Eminences aren't all they're cracked up to be. So far in this amp I've had a Red Fang and then a Weber temporarily, and now the Tonker. I've only noticed it with the Tonker.

So, does this happen with the B only on the low E? If it doesn't happen on the 2nd fret of the A string, then I would start looking into guitar/pickup problems.

i think the speaker is just reproducing what is coming in. The Tonker probably just does that better than the others. I'd be looking at tubes being the problem. Try this amp with an outboard speaker, perhaps it's an interaction with the speaker and the chassis. Be sure your pickups aren't too close to the strings. Worst case it's caps.

Doesnt happen with my Mazerati with Celestion Blues at all. It had some shrill overtones on high notes when the speakers were new, but after some break in time that went away.

I've had something like that happen before. It was an EL84 power tube going bad. I've also had it happen when a phase inverter tube was going bad.
