guitar amp head combination

Well, it depends on many things actually. I'm far from good guitar tone wise but I like to blend my 6505 & my Marshall 8100 when I quadtrack. Both at each side. Or 5150 III at one side and 6505 at the other side.
 
I was going to post this same kind of question, anyway how do u guys usually blend the amps? For example, do you set one amp to have really punchy mids and back off the highs and bass, then set the other amp to have this really scooped sound? I tried this before but end up with a really anal hollow guitar sound. Mainly for quad tracking, both amps at each side.
 
I do it all the time. you can listen to the songs on my soundcloud. The Radial JD7 does that kind of thing. You can hook up up to 7 amps, i guess, and treat every amp in it´s own way (like Deathell asked), by using lets say a Diezel for the wide/thick sound, 5150 for the "bite" and mids, and maybe another to even out the top end or just go with 2 amps, that´s what i do.
I use a re-amp box, the radial (yellow). When reamping i can hook up 2 amps (there are 2 outputs) that run at the same time. Oh, and don´t forget to check your phase switch!
 
I'm a cheap bastard, so I derive my tone right now almost entirely from free VSTs. I'm happy with it, so I'll share it. I have both rhythm and lead tones dialed in in this manner:

RHYTHM - LEFT

- Boss TU-2 Tuner.
- Boss NS-2 Noise Suppressor (good noise suppressor, saves processing power as well).
- LePou Legion Amp - Sometimes I use a TSE-808 OD in front of the Legion, which it doesn't really need, but adds that bit of saturation that I tend to like. Just a little bit though, and definitely not always.
- LePou LeCab 2. I use a Fredman impulse coupled with an edge mic impulse. The Legion is a very bright amp so the edge mic tames a bit of the highs and adds some bottom and mids. I also use the low and high pass filters and no more than four cabs at a time. I find any more than that just makes the guitars too loud after overdubs are layered.

RHYTHM RIGHT

- Boss Pedals
- TSE 808 OD
- LePou HyBrit - That's their Marshall amp simulator. It needs a lot of help from the TSE to get a "metal" tone, but once you dial both of them in, it has a lot of bite and bottom end that compliments the natural brightness of the Legion really well.
- LePou LeCab 2. I also use a Fredman impulse coupled with a straight cone impulse. This actually adds some highs since the HyBrit has so much bottom end, and balances the tone nicely.

I don't do much EQ'ing to either amp. I simply try to tone down the bad and accentuate the good of each amp. I use my Les Paul exclusively for rhythms as well, so I try to dial everything in with the guitar in mind.

LEADS

- TSE 808 OD
- AmpLion Rectifier Amp - This is a GREAT plug in. Highly recommended for leads. This is their only free model to my knowledge, and it's awesome. It has a certain clarity that just works really well for fast lead stuff, and you can run up to two cabinets, so you can get a lead tone that competes with a lot of rhythm overdubs right off the gate.

I use my Jackson Rhoads exclusively for leads. Both guitars have a Seymour Duncan JB in the bridge and a SD Jazz on the neck.
 
I used to be all about v30 cabs, specifically found I had the best results with Framus Dragon or Orange cabs with those speakers, but now I'm all about Marshall 1960A's, preferably with a 5150 1/2/3 on top. Currently in love with MI Audio Megalith heads and Bogner Uberschalls as well. Been doing a lot of stuff with some vintage JMP's boosted to hell lately also.

Also used to be really into the SM57 thing but nowadays I'm always going for a couple of 421's instead.

Depends on the project really!
 
Usually something fat/smooth with something crunchy/aggressive....or something with juicy mids and something that can be scooped nice (5150/Recto comes in mind here as a classic combo).
 
How would you go about phasing? How do you know when it's in phase or not. Sorry for such question, I'm still newb at this.

You can flip the phase. Most DAWs have a button on the channel for this.

Or, you can zoom in close on the waveform and check manually. You can slide one track forward or backward by a tiny bit to correct any thing that is not in phase, but I'm pretty sure this isn't quite the proper way to go about it.
 
There's always a lot of 5150/6505 love around here. Maybe mine is broken or needs servicing, but anytime I break it out and try it, it always seems thin and lifeless.

My favorite amp is the Mesa Mark IV into Mesa OS cab, so far. I haven't gotten to try many awesome amps though......
 
People certainly love sounding exactly like everybody else around these parts!

There is a lot of sim/impulse love here too.

You'd be surprised at how many people can't mic up a cab, even with the tried and true rig like mine. Tone is in the hands too, which is why my tones STILL don't touch Sneap's.
