Help: My Rectifier sounds different each day!

I'm having this happening to me a lot. One day I set the sound and i'm happy with it and the next day when I come back it sounds totally different even when the setup is still the same. Di'd not change ANYTHING AT ALL. It almost sounds as the mic was moved but it was NOT (100% shure).
I also changed all my tubes, but this still goes on...I also run a Voltage regulator. I've also experienced this with other guitar cabs then this one.

Here's a clip of my Rectifier one day and then the next day. Sounds different!! The first day it sounds darker voiced and way cooler, the next day it sound fizzier. Exactly the same setup.

How long have you had your amp running for? Amps sound different after tubes get warmer, tube microphones do too.

Try putting up a Sennheiser 421 as well. Then you'll only be 50% shure

Maybe the humidity of your room is having an effect?

tubes (amp & mics & effects), temperature, humidty, the gtr itself (temp & humidity), and time of day (unless you have isolated power) ..jmho

You forgot to consider hearing fatigue.

You really have to watch the length of exposure to sound.

It's going to sound different depending on how long you've played
and how long you've given your ears a break.

It could also be something as simple as a defective tube breaking down.

First, Change the filter caps. The real problem is it’s a Mesa Boogie. No offense. Isn't anyone sick of that sound yet? It sounds like the rear end differential of a waste management truck on a Sunday morning. like a guitar through a 4 inch speaker and a cheese grader creating one sound together. But other than that, I guess it sounds great.

SO TRUE, couldn't agree more.

You couldn't possibly understand how funny your request is unless you'd
followed my posts about severe hearing loss.

Keep it up and you'll end up just like me.

My clip contains two samples. Some playing from one day and some playing from the day after. All playing is been done reamping the same section, so it's not my playing either.

You can't hear the difference? It's really easy to hear, man...

I listened all the way through twice and couldn't hear anything much different.

I've played more hard rock than you could ever imagine and I'm telling you straight up,
and no kidding around, you're gonna hurt yourself if you keep it up.

Edit:

In all honesty, most of us old timers kinda wish death metal would live up to it's name.

I'm not trying to be insensitive or mean here, so please don't take it that way.

Not only could you be suffering from hearing fatigue, but even a slight difference in
tuning accuracy can make what you think is exactly the same, change a bit.
Also your attack may be just a bit different enough to affect the tones you're getting.

The only fizzle I can hear is coming from my own cursed ears as it has been for the last 12 years.

So True!

The difference is so minimal, the change in room temperature; air vents blowing, etc. all can cause that ever so minor change. In a track, especially the kind of song that would have those type of guitars, a dog couldn't hear it.

FETT & 84K - how old are you? OK what age group are you in?

I'm starting to get scared because I can hear pretty much very noticeable difference, mostly on the top end & those are the frequencies people stop hearing with age. OK it's not some phenomenal difference, but pretty damn noticeable.

I don't own a dual rectifier yet. Listening quietly on my laptop there definitley seems to be a difference.
IMHO
sample #1 has more of a mid range punch. Darker.
sample #2 has more top end presence.
Bottom end seems the same on both.

Sounds different enough that I'd suspect someone of having altered the mid range but especially presence/treble knobs. I personally prefer #1 and find the difference substantial enough that I'd be annoyed if I had to punch in the next day.

Sounds great but if this happens regularly I'd have it looked at.

Do you notice a difference just playing the amp, or do you notice it only when recording? It really sounds like the mic got moved like a centimeter, or maybe even the cab got bumped. I don't hear anything "wrong" with the sound in either case.

I listened to the samples and that's definitely more of a difference than I've ever heard from just temp and humidity alone. Sample 1 has quite bit more midrange presence and bite, and will cut through a dense mix much better.

My first two thoughts on the change in tone are that your mic or the amp got moved slightly, and not put back in exactly the same place; or you tracked one of those after the amp had been on, and the tubes had been cooking a while, and the other one shortly after powering up.

Good luck in running this one down.

You might need a line regulator to keep your voltage the same.

I'm on a fast track to that double nickel next year as far as age, so yeah, I'm geezin.

My hearing wasn't damaged from playing live, it was from excessive use of headphones while recording back in '94
It wasn't the volume, it was the excessive length of exposure trying to record
for hours on end at all hours when the house was quiet.

I'm now profoundly deaf in my right ear with maybe 50% remaining in the left ear.
I've spent over $4000.00 on specialists including THE expert at Johns Hopkins.

So yes when I talk about hearing loss, I'm serious as a heart attack.
My ears haven't stopped ringing since '95 and I went from having perfect pitch
and no hearing issues, to this freeking nightmare in less than one year.

The tinnitus is so overwhelming sometimes, that it acts like a frequency wash
cutting out what little I can hear.

You full timers really have to watch it and learn to take silence breaks, for days and weeks in some cases.
Remember that no artist and no recording project is worth destroying the rest of your career.

Use headphones at the lowest possible volume and then limit exposure to necessary
tracking and brief mix checks. Use your nearfields and then try to limit exposure.

Obviously, use professional hearing protection in live situations.

This is truly maddening and I just don't want any of you guys in this community to end up like me.

That's what it sounded to me like too. Top end became smooth & overall warmer sound as tubes warmed up.
But it really could be so many things.

Trust me. My hearing is fine. The difference is there, but post the different takes in a full song; drums, bass, and all the other doubled guitar parts that I am sure would be there. Then let's hear how noticeable the difference is.

That's quite a difference. It's not subtle at all. Can you hear it when you're playing, or only on playback? I'd say it's too much to be accounted for by a change in humidity or temp. And you're 100% dead-on, bet-your-life sure that nothing was moved, not even a 1/4"? Was anything else in the room moved - including yourself? You might be picking up or blocking a reflection somewhere. If those factors are all exactly the same, I'd have to say it's due to the length of time the amp has had to warm up. In my experience, there are huge changes over the first 1/2 hour or so, and noticeable from 1-2 hours.

And I don't think your amp is malfunctioning in any way. I wouldn't change tubes or power caps at this point.

Defintelly a difference, second clip was much brighter, I wouldn't call it fizzy, just brighter. To narrow down the issue, I beleive you said you just reamped the same track, just on a different day, so the playing and file is the same, the only changing variable is different days with your amp, and you are sure the mic did not get moved one bit, though If you are hearing it yourself day to day, that helps eliminate the mic has moved.

You can hear the difference in the room, and not just through an isolated mic'd situation?

Is the amp on for the same amount of time when you play it, ie, one day the tubes have been warmed up longer?

what brand of tubes to you stick in there, same bias?



My first guess is that possibly you have another bad tube which can explain the loss of definition, or worse, a bad socket. Does the amp exhibit this on the other channels, or just the drive channell?
both clips sound good, just its quite a difference from day to day no doubt.

Problem occurs both before and after tube change. Bias is set correct/same.
I moved NOTHING in the room.

one clip is way darker while the other is whimpier.....
Warming the amp up for an hour di'd not help.
I also run a furman 30A voltage regulator.

This is crazy!

Oh, and another thing...people rave about 1176 rev this sounds sooooo much better then 1176 revision that and old vs new 1073 bla bla bla Focusrite sux... those preamps rule so much more then those other preamps yada yada yada, but you can't hear a difference in THIS (the guitar clips I posted)?!!!!! Who the hell are these people, just "talkers"? -I- have a hearing problem? - yeah right!!

I use a singal rec in my studio alot, plus live, and Ive ALWAYS said it has good days and bad days.

I always just put it down to the voltage of the place im in, temp, etc.

My 2p is to leave it on standby for a good while and try again, its worth a go.


Mines never been a problem during sessions, just more like one week Ill plug my rig in and go, "this sownds sweet!", and the next week it'll be, "pah, my amp is crap."

Good luck!

yeah, that is kinda funny dude. I hear ya. So strange for such a dramatic sound change. Maybe just another wim, but try using a different cable going into your amp if you havn't, and different guitars and see if that replicates the issue.

once again, I don't think either clip sounds bad, just rather different from teh same settings. I have heard mesa recs are very picky about their sweet spot. I have a mesa F-50 and I like it some days, others i don't.
