Bman and T/D hum in channel A

[bscfo1]

Does anyone else notice this? With a low gain of about 10:00, and a module master level of about 2:00 or 3:00, these two modules will hum in my MOD 100. None of my other modules do this in channel A. My DLX and VX are completely silent with the same settings.

I've moved them around to different positions, as well as moved the amp, changed tubes, used different guitars, nothing changes. I really love these two modules, but this drives me nuts.

Funny thing is they both quiet down when I max the gain and back off the module master. This works, but you lose the prinstine cleans.

It's MOJO PM sent Bill!!

Thanks Jason for the response. Only one person so far? I wonder if only the MOD 100 does this. I know most of you have MOD 50's. The hum is not real bad, but you sure hear it when you record.

Even my SL2 is dead quiet in channel A.

Anyone? Jeff? Bruce? Frank? Help!

I would imagine this is as a result of diming the Module master. Understand I do not own a MOD100 but I had a similar issue with my M4. You could try a lower gain pre tube like a 5751 or 12at7 in V1. You then have the option of increasing the gain and therefore the volume. Just a thought...

 

[bscfo1]

Thanks for the response. You're right about diming the module master to hear it. But mine will do it even at a reasonable levels as long as the gain is anything BELOW max. Strange. I'll use a setting similar to what is shown at Indoor Storm's demos when they are using a clean setting. Low gain, (10:00) module master around 2:00. It's still there.

And the curious thing is if I dime the gain (!), it's quiet as a mouse at any level. Try it.

I did try a different set of tubes. I even did as chode7 (LOL - There are 6 other "chodes" out there?) suggested with the 5751 preamp tubes but it's still there.

It only happens with the Bman and T/D modules. I can use the same settings on other module used for clean (DLX, VX) in channel A and they make no sound at all.

Also, diming the gain makes it go away(!) which you wouldn't expect, and then you lose the chime.

Mine does this on channel A also in the Mod 100/50 and M4.I didn't really notice it until it was brought forth and I use very little gain on the A channel and more master,haha too tell you the truth,I really live on the EG 5 But noew I'm curious as to WTF that buzz is.Does anybody else get this?

47 people have looked at this and only one person other than me has confirmed it. How can that be? Jason from California and Bill from Florida are the only two apparently with "special" modules that hum to themselves.

Please test your Bman's and T/D's for us. Module gain around 10:00, module master around 2:00-3:00, amp master any freakin' where.

I can't record with this thing going buzzzzzzzzzzzzzz.

PLEEEEEEEEEEASE

Well I just emerged from the man-cave and I honestly can't tell ya what the root cause is of your problem. I spiked the master on my BMAN and rolled the gain back to 10'oclock and my shit is dead quiet. I mean DEAD quiet. I have the grill cloth yanked off my cab so my ear was 1" from the cone. I was thinking maybe it was a bad cord but it's isolated to the clean modules. Have you tried putting the modules in a different slot?

Mine follows the module(bassman)in the 100/50 and M4 Thanks for the reply anyone else's not buzz

If I have this issue, i don't notice it since I use a noise gate in the loop right before my delays.

well go turn that noise gate off man

Ahh, we are getting a few responses - thanks. Chode7: I moved it around just as you said. It doesn't seem to matter what slot it's in. Still hums exactly the same. Remember, I don't dime the module masters and the gain is only on about 10:00. These are not extreme positions for a nice chimey clean. My DLX and VX set like this are dead quiet in channel A.

I actually recall some people were having trouble with the levels between clean modules and high gain ones. Most of the advice called for you to set everything around the clean modules, and this mean that you have to run the clean modules masters up high and the gain low if you want a pristine clean. This is normal and it shouldn't buzz.

Also it DOESN'T buzz with the gain maxed which really makes no sense. Should be the opposite. Please check this out.

Now this is brought up,I seem to remember something about this noise(buzz)before but I could be mistaken The Bman sounds so good on the A channel when run clean!!!

I ran my Bman with the gain around 11-12 o'clock and the master between 1-2 o'clock and it was always dead quiet. I would run the gain back around 10 o'clock and dime the master and was still silent. I was also using NOS GE 12AX7's though, it sounds like a classic bad tube issue to me, even though you've tried switching them. Have you tried putting tubes in the Bman or T/D from other modules that you know dont hum?

 

[bscfo1]

Thanks Valtiel - I did put different tubes in there, but I like the way you think. I'll try the tubes that are in my DLX - it is completely quiet with the same settings. -Bill

This is throwing me. I got nothing. PM Jeff. Might be new module time. Who knows maybe you just need to replace a resistor or something. Check the board for anything loose I guess. Maybe a bad solder connection. I know I'm playing with fire even suggesting something like this but I suppose it's not out of the realm of possibility. Did you get this thing used? Have you modded anything? Other than that you stumped me.

 

[bscfo1]

The "no buzz" with max gain is what is so weird. It's like the buzz just goes away at about 95% or more gain and then it's silent no matter where the module master is. So I've been running both the T/D and the Bman like this on channel A because the buzz is driving me nuts. It still sounds good but I shouldn't have to do this. It is less chimey, more warm, but sometimes I just don't want that. I'd really like to use a lower gain setting on channel A with no buzz. Maybe jmgman69 can explain it better than me. Jason - I may need your help.

I started this thread because I'm frustrated with this problem. I've already set one T/D back to Jeff and he was very helpful at that time and set me another. The one he sent me did the same thing - exactly. I didn't even want to address the Bman until I got to the bottom of the T/D problem. How could I have three different modules direct from Egnater that hum exactly alike? Impossible unless somethings wrong with one of the components.

Now I want to know if anyone else is having this problem before I talk to Jeff again.
