To be honest, I don't even remember why the amp was sent back the first time or what the complaint is now. From what I've been told, there was nothing wrong with it the first time in. The tech. burned it in for a day and played bass through it. This particular tech. is probably the best there, but he's not really a bass player, so maybe something was overlooked that an actual bass player would pick up on.

These are built to order, so there may not be a new one in stock to send out at the moment. The assembly line is reconfigured depending on what's scheduled for production on a given day. At the same time, Peavey manufactures the whole amp, so the chassis from the metal shop, cabinet from the wood shop, circuit boards from the PCB line, etc... must be ready before assembly. Most likely, the option with the fastest turn around time was offered. Also, in these situations (repeat offender, upset customer) service turn around is usually expedited.

You were told nothing was wrong with it? Because the paper they sent back to me said that there WAS an issue and they did indeed fix it.(intermittent signal in the power section) But it was simply one of a few different issues. I'm thinking maybe there is a communication problem somewhere?

When you send it in, include a letter clearly identifying each problem as you see it. Explain carefully what exactly is happening to the best of your ability. The more information you can provide the better the final result will be.

All of us who have done tech work have had very vague symptoms described to us. We all do our best to service the unit back into a proper playable state.

I had a Marshall tube amp brought to me once. The problem "It blows the power fuse!". On first inspection the power fuse was indeed blown except the fuse was wrapped in cigarette foil that had melted. The HT (B+) fuse was a piece of a nail. To repair the thing I had to replace the burned out power transformer, the burned out output transformer, repair the failed bias supply and replace a whole bunch of other small parts. The tubes were also toast. The customer was not a happy camper when he saw the bill.

I'm so glad I don't do tech work anymore.

I have a customer with a Marshall 6100, first time I saw it I told him the OT was damaged (shorted 8 ohm tap). Four years and three sets of output tubes later he finally had me replace the OT. Guess he got tired of cooking tubes and replacing HT fuses when someone would bump the impedance switch.

Well I got an email from peavey just a second ago, it looks to be maybe GC was right after all. Because peaveys email told me that turning the gain or master up all the way gives me the cleanest sound possible. At least if I'm understanding this correctly.


"Austin,
Turning the post gain or master volume up high gives you the cleanest sound whether you are talking about bass amps or guitar amps or even mixers...
The honest truth is if the Guitar Center people have issues with your settings then they are probably right! Can you get the sound you are looking for with less noise by setting the Master volume lower? Probably."

Copied from the email. Guess I was wrong after all!

I know it stinks to have these sort of issues and be without an amp for a length of time, OP, but you do have the man who designed the thing trying to help you here, I'd take advantage of that. Not some tech in Houston, but the man that designed your amplifier. That means he knows more about the amp than anyone on this entire planet, and by extension, anyone....period.

Unless of course you not only believe in aliens, but also believe they are operating a pizzarro Peavey company somewhere in another galaxy, with a pizzarro BobbyBld designing pizzarro VB-2's. :D

Borrow or rent something in the meantime.

I think I mentioned it in another thread, but if you were just a little more local, my T-Max would be yours to use in the interim, so you wouldn't even have to miss out on any of the goodness that is Peavey.....(hands off the Classic400 though). :D

What is your current issue with the amp...I noticed the master volume control seems to be involved?
Click to expand...

I get lots of rattling from something inside the head, and its also causing my pickups to become super noisy when I put my hand near them. I've tried my bass at different guitar stores and No matter how cranked the amp is Its dead quiet. Those are the 2 main issues.

But if you really don't think there is an issue with it then maybe I really am just using it wrong.

Hmm......post gain high/pre gain low is the recipe for clean tone and headroom but also possibly increased noise/hiss. It's almost impossible to know the sound you're describing without hearing it for one's self, but what is it to the best of your ability. Hiss? Very loud hiss? Little bit annoying in a quiet room by yourself but inaudible while playing?

Most any amp can induce some noticable amount of noise with controls set extremely high but it shouldn't be all that bad unless you've some grounding or interference issue somewhere. Tapped in any preamp tubes with a pencil eraser?

Noise with hand near pickups can indicate a grounding or some weird magnetic or RF interference thing.



Edit: I guess Bobby's online. The little green light is off so it looks like he's not here. Listen to him, not me.

JellinWellen, my turn to visit your thread...
It seems we have the same or similar issues. Since mine is a NOS 2008 and shipping from Sweden to Bobby at Peavey is not an option, I am really on the fence. I can only keep it a couple of days more before returning it ($90 shipping) and if I keep it I will at least need a set of output tubes ($90). And there might still be the interference issue similar to what you have. Instrument dependant noise even with the gain turned all the way down. I really wanted to like the VB-2 - it was ideal on paper.

Peavey has replaced my output tubes twice. The only thing it fixed was the intermittent signal popping I was getting, what makes you think its the power tubes?

What sort of noise?????????????


The interference you guys describe with your hands around pickups even with the gain down can be some weird magnetic thing with the pickups for some shielding not being connected around a transformer or something but that magnetic stuff usually shows up as a sort of hum.

RF interference from the same lack of shielding can be static, the "radio set between stations" sound or even picking up actual radio stations.


The better you can describe your problem, the better chance anybody has of pointing you in the right direction. Tubes ain't always the problem.

I'm not picking up radio stations but I would describe it as a more of a crackly hiss.

Not trying to be a prick, just draw out more info. "Noise" can mean a whole bunch of things. Guess it's just one of those somebody has to hear for themselves.

There's nothing at all wrong with diming master and using gsin for volume. Least distortion/most headroom that way but along with it comes more hiss. Some OD channels can bring a good bit of noise with high gain and treble usage.

I set my amp that way to get the power tubes to distort slightly, not for clean volume. Its actually quieter to do that on my amp. Whenever I do that the pickup noise is gone, for example:

OD channel
Gain 12 o clock
master 12 o clock
The pickup noise is very present

OD channel
Gain on 7 o clock (very low)
Master dimed
Slightly more noise from the amp, but no noise from the pickups on my bass.
But when I run it like this, my mute button doesnt mute the signal all the way anymore.

Thats what leads me to believe the problem lies in the preamp section of my amp.
