So if i have my mesa boogie f-50 (i bought it used yesterday) at clean, and play whit my guitar with passive dimarzios, i get a complete clean sound. If i plug in my other guitar at the same settings with emg81+85, i get overdrive, or distortion.
How do i clear this, and why do it happen?
Also if i use my guitar with passive dimarzios, and turn the volume and gain up i also get overdrive/distortion, how do i clean this up? I like to have my clean channel completely clean, and the distorted channel very distorted.
How do pepole play loud and completely clean?

This is probably some very stupid questions, but i hope you will answer them. Also this is my first tube amp.

turn down the volume on your guitar humbuckers will distort unless you turn them down

Yeah, EMGs (and other active pickups) have an active preamp built in. Imagine playing passive pickups with a 20dB gain boost in front of them. Thats an EMG.

to get more headroom, all you really have to do is turn the volume down on the guitar or use a volume pedal.

roll down guitar's volume knob (a treble bleed cap will help retain treble)

pick more gently

on the amp, i forget the exact layout of the f-series, but if the clean channel has a preamp gain knob, keep that low and compensate by turning the master and/or channel volumes up

try those and see if they work

EDIT: EMGs have massive output, they're not helping matters.

This. I imagine that the OP's other guitar has pretty high output pickups. I experience the same thing sometimes with my Ibanez Jem (you can't get a true clean sound on a clean channel of an amp, especially if the amp is lower wattage), and the problem is only solved (short of volume knobbing it) if the amp lets you control pre-gain. Otherwise, the only things I can think of are little tweaks like lowering your pickups.
#9
ah yeah lowering your pickups a bit would help too, good call.

but try the preamp gain/master volume thing first, as that's the easiest and might accomplish what you want on its own.

If you want cleans that will not break up, you unfortunately need to go Solid State. It's simply a property of tubes that they start to distort as they're driven harder, even on a clean channel (Some of my favorite overdriven tones come from disregarding the "dirty" channel, and just cranking the clean channel as high as it goes). You need to lower the pre-amp volume("gain") and you wont be able to crank the power-amp section all the way, either("volume").
As for keeping your active pickups from driving the amp unnecessarily, your only real option is to turn the volume down, either on the guitar, or with a pedal.

Uhhhhh, not really...unless you're talking over 500 SS watts. If you have a 120 watt tube amp biased cold, it wont have much power tube distortion at high volumes...A 120 watt SS amp at the same volume would prolly distort much sooner, and sound like crap depending on the design.
#13
This is the case with a lot of Mesa amps. You basically have to set your master high and then the channel gain AND the volume quite low.

Experiment with the mids and the bass as well as the higher they are the earlier you'll get breakup. Also the more you jack the treble up the more gain that will introduce as well.
#14
Yeah well, as pretty many guys said above, your guitar with the active EMGs will make the drive the amp more...

I have personal experience of this since a friend of mine has an ENGL e530 preamp and he has a J-50BC with a JE-1000 Boost in his guitar. His sound was quite distorted with his settings but when I plugged in my guitar, which is a stock Gibson LP Studio (passive Gibson 490r/498t pickups), the sound was little more than just overdriven, but not really high-gain metal sound.

I had a mesa f50, and I never distorted the clean channel. I have blackout, and those are much hotter then EMG. You just have to play with the settings. make sure the clean channel gain is almost all the way down, and turn up the master. That should clean it up

Hey cool dude. I have a problem that the distortion channel sonds to muddy. I can turn the treble and gain almost all the way up and bass and mids almost all the way down, and it still fells muddy and not tight. Therefore i use a metal mudf pedal instead. Did you face this problem? Shuld i change the tubes?

If you can't get a loud clean sound out of a Fender Twin you are doing it wrong. If you have a tube amp (with a few notable exceptions) 50W or more there should be no problem getting a loud clean sound out of it. If using EMG's you may have to back off the guitar's volume a bit so the preamp isn't being overdriven but you should still be able to get loud and clean. Saying you need a SS amp just displays user error.

Change the tubes and run a tube screamer. Alot less gain. Like I'd say 1 oclock max on the gain (with a tube screamer) and try eqing the amp again.

Also if you can get rid of the EMG's. I used to be an only active pick up guy, and I've used them all 81, 60, 85, 81x, Blackouts. All of them, and they're just to much with most hi gain amps.. Like I understand active's into an Orange or a Marshall cause they aren't really gainy amps, but with amps like Rectifiers, and the F series ect, Passive Pick ups and a Tube screamer is the way to go for Hi-gain and keeping a tight clear sound.

You found out the point of a gain knob! That's what it's there for, the clean channel plus gain won't be clean.

and the treble all the way up.

This, missed the whole mids thing.

There is never a good reason for scooped mids on hi gain. I'd never turn them lower then 10:30.

mids help tighten the amp

I tried having alot of mids too, it still sounds muddy. It may be because i have a very low volume.

What would a tube screamer do? Is it like a distortion pedal?

Also problem with the emg guitar might as well be the guitar. When i changed battery, i was getting distortion. The signaal is always turning on and off.

But yeah, can the low volume on my amp be the reason the distortion channel sounds muddy?

set all your EQ knobs at noon (pointing straight up, not actually adjusting them at 12:00 pm) and play a few riffs. Tweak each knob a little at a time to see how it changes your sound. A lot of mesa amps have VERY sensitive EQ. Meaning that a minor change will have a big impact on your sound, and may even require you to change the other knobs to compensate. But once you find the sweet spot, they sound great.

The tubescreamer is an overdrive pedal. It gives a little boost ahead of the preamp, and is generally used to tighten the amp, and lose a lot of muddyness in some amps. If you get one, keep the gain pretty much at 0, the volume (or level... can't remember how it's labeled) maxed, and tone where you like. Start out with that and play around. You'll want it off when on the clean channel though. It'll add a little grit to your cleans.

But can the muddyness come from that the amp has very low volume?

a) Lower the gain no the clean channel, increase channel volume
b) lower bass, boost mids, boost treble
c) use the dang bright switch

It can be part of the problem, moar volume always helps, but thats not all it. Tubescreamers are an overdrive pedal, you put it in front of the gain channel to get more distortion without cranking the gain, to much amp gain makes mud. Set the tubescreamer to the gain all the ways off, all the pedal volume, and the tone just past 12 oclock

The f series only have a gain and a volume for each channel. There is no channel volume / master volume.

Do you have the contour on? But that kind of amp setting sounds pretty bad. EXPERIMENT: mesa's eq'ing is difficult to master.

Tube screamer tightens the sound be cutting bass, bumping up mids.
I also found my f30 came to life with the volume at about 10 o'clock or higher.
A tube change made my amp sound a lot better too.

The more mids you have, the bass frequencies are less audible, thus bringing a tighter sound. Try it on your amp, slowly bring the mids down, you'll hear more bass as you do so and you'll get more mud.
