Moving in STEREO! *** VIDEO ADDED***

[D-Rock]

As mentioned, you may encounter phase issues and ground loop noise, depending on your specific setup.

If you do, you will want a pedal that allows you to keep running a stereo setup, especially after you experience the sound of stereo.

This is what I use, it has ground loop switch and phase switch. Also has a "Drag" dial which fine tunes the input level to adjust the for varying signal strength between amps and pickups.
Bulletproof and under $100 too. Other pedals of the same quality and same features like from Lehle cost twice and even triple as much money.

a)If its out of phase the speakers are no good??

b)Also when testing should you do both positive to positive and then positive to positive to see if the speaker goes both outward and inward?

a)No ... they are just wired out of phase. Reversing the positive & negative wire will change the phase.

b) Not sure what you are asking ?.....

Using a 9 volt battery and a speaker chord connected to the cab...
Positive battery terminal to the Tip of the 1/4" plug, negative battery terminal to Sleeve. This should make the speaker cone move outward or inwards. As long as all the speakers are same (out or in) the speakers are in phase with each other.

As mentioned earlier, switching channels in your amp can change the phasing as well.

Wet dry rig is simple and easy. Still sounds massive. And by slapping an EQ and delay in the send loop going to the second amp, you can have them sound a little different. I spike the mids a bit.

Not sure that a poorly implemented two amp rig sounds as good as a well don't wet dry.

Thanks this clears it up a little, sorry for being a noob.

For B)...What I mean is in the video. He checks phase pos. to pos. speaker pops out. He then checks again pos to neg and the speaker goes inward. I was asking should I be checking both of them as well?

I am realizing I put pos to pos in both scenarios and I blame that on using a cell phone and too much smoking.

It's dangerous.

Think I am gonna run it Wet/Dry with the Graphic EQ pedal and chorus running thru the loop of the recto.
It has a better loop then the Peavey.
But yeah.....cant wait for the weekend to check it out.

Not necessarily.

pretty sure the drag control is variable input impedance which should only color the tone; not balance levels between outputs. FYI.

ok dan-it's saturday. i know you work today, but we need an update.

 

[stephen sawall]

Now that Dan has tried out 2 amps at volume he does not need this forum anymore. We might never see him again ?

Well I tried it out last nite.....
started dialing it in.....had the Delay in front using as the splitter.
Had about 15 minutes into it....
The Windsor Blew a fuse a died.

Just got back from Home depot with new fuses. Gonna fire it up again in a few.
But from what i heard....WOW! Very thick....like 4 amps...4 cabs....
very very cool! But then the bubble popped.

Not sure what happened. The main fuse that powers the amp up.
Oh well....used to happen to me all the time with my Randall RM100. At least once a week.

 

[stephen sawall]

When using more than one amp I think of it as 1+1=10.

I was doing a three amp rig doing all kinds of crazy stuff with my GCX / GCP. Mesa Mark IV & Fryette Sig X as left & right. THD Flexi as center. I could switch in any single amp or combination. The phase problems made me little crazy ...

 

[Mailman1971]

It actually sounded REALLY GOOD! No Phase issues.
Put the new fuse in..........amp lit right up...
only to see that one of the power tubes blew.
Oh well.....will make it happen soon. Too bad I sold all my extra tubes.

With a stereo rig, you obviously need another amp. Your backup! Now what can you get cheap, and send to Jerry.....?



Glad you had the Madison square garage glory raging for a bit.

I'm sure it was Epic

 

[stephen sawall]

Dead tube .... it happens. I always keep a few tubes around.
The wall of sound that can be created with more than one amp can be impressive. It certainly does things no single amp can do. The girth is unreal.

 

[petejt]

So how do you folks EQ these amps so they blend effectively?

 

[Heritage Softail]

I put a delay and EQ in the effects send of the dry amp. Punch it in to boost the mids.

Waiting to get the Kemper and profile two amps.

 

[stephen sawall]

So how do you folks EQ these amps so they blend effectively?

I start by setting up the amps the way I usually do .... then I just fine tune them so they sound right. I messed around with trying to make one cover the lows & the other the highs / etc. But to get the fattest sound I do it the other way.

I tend to set up all amps so they kind of sound the same .... no matter what amp I use. Similar amount of distortion. By blending preamp distortion & power overdrive in each amp. Same tonal balance.... usually a bit bass heavy with a lot of midrange. Just enough highs to cut.

To get the best results I usually use a amp that is more poweramp overdrive & the other amp more preamp distortion. The preamp distortion amp will do a better job of covering the highs & lows with more compression. The poweramp overdrive amp gets the thicker midrange & dynamics.

It really isn't any different than using the tone controls on a single amp ..... but you get a lot more control. Finding the right balance is the trick.

I do not mess with any effects till I get the balance right with both amps dry. Then I use whatever effects out in front of both amps ..... but only effects in the loop of one amp ~ this would be the amp with preamp distortion / not poweramp overdrive.

You can run both amps a bit cleaner than normal .... because both will thicken up the sound. This also gives more definition.

The real problem comes when you do a show & you have no control over how the person mixing blends the amps .... good luck with that issue. I did this live most of the time for about 20 years ... So I am pretty familiar with how it works.

 

[Mailman1971]

Yeah I only messed with it for about 20 minutes....wasnt TOO hard to dial them in to blend. Sorta left my settings alone and then was messing with it. Was more or less setting up the DD3 to make sure it wasnt panning too fast or slow. Thats where the "girth" secret comes in I am finding out.
Just gonna pull the 2 tubes and run the Windsor at 50 watts.

if you pull 2 inner or outer tubes, make sure you bump the ohm setting on the head one down from what you had it at. if you were at 16 then go to 8. if you were 8 go to 4.

try dialing one amp for lows and one for mids and highs....then switching that......then try just blending them with less distortion than you would normally (as was mentioned). there's all sorts of cool stuff you can do with a stereo amp rig or a wdw rig.
