Everyone I have called has no idea! And no, I don't mean how do I use two different cabs with one head.

I gather you want to run two heads into one cab, not how to run two heads in tandem? (i.e. different heads into different cabs with one signal)

correct

I honestly don't think there is a safe way to do this unless it's a stereo cab...then again, I've just never done it before.

In other words, I'm extremely open to being wrong.

Well, I currently have three cabs and two heads. So how do I play through the two separate rigs at the same time?

Pee on it. Problem solved

I have two heads and four cabs and I run them all just fine.

What is the ohm load of each cab?

8 ohms. I now know what "dc" stands for. Dour Cursiva! hahaha. Completely forgot we used to play shows together.

and okay so you run two heads and four cabs at the same time...how?!

ah, ha

ok.

so you're going to have to make a choice.

One head will have to go into one cab. Obviously out at 8ohm.

The other one that you want in two cabs will have to be sent with two speaker cables @4ohm each.

When running two cabs, they have to have the same ohm rating. And the maximum load you run from your amp has to equal that number (in this case 8, so 4+4. If the cabs were 16ohm, you would run 8 and 8)

However, you can't run both heads into the third cab to have a blended signal unless there are two stereo inputs (most Marshalls have this).

I used to run 2 half stacks together using an ABY box. Morley makes them for like $40. I'm not sure if that answers your original question though.

signal is split with an A/B/Y pedal to run to multiple heads. (should have mentioned that)

Head one runs into two 16ohm cabs, two speaker outs @ 8ohm each.

Head two runs into two 8ohm cabs, two speaker outs @ 4ohm each.

I would love to hear what this will sound like.

Yeah, the A/B or A/B/Y box thing is a point I managed to gloss over.

I focused on the ohm thing because I think a lot of people are ignorant on the proper way to deal with it when running two cabs from a head.

HUGE AND WARM.

OOOHHH okay so its the A/B/Y box that I am going to have to purchase. Thank you!

Yeah there was no way I was planning on running three different cabs into one head.

I'd never actually stack them like this, but this is my junk

What are your review on the BadCat head and Orange cab? I'm planning on selling my cabs for an Orange cab. Also, I wanted to sell my Mesa for a Marshall JMP but, I have grown quite found of it over the years

The Bad Cat is absolutely retarded. Go play them at Boston Guitar Works in Brockton. Expensive as all hell, but you can hear that it's a class above. I had some issues with it recently, but got those resolved. I actually run KT77s instead of EL34s to bring the gain down and up the headroom, which works really well for what I'm up to now. If you can afford them and you like the sound, I can't really recommend anything else.

I like my Orange cab, it doesn't have that modern, tight low end that you get from Mesa, but it's definitely a quality thing. Has a nice loose vibe to it. Very heavy...physically.

Behringer cabs have stereo inputs, so you can run one head into 2 speakers and the other head into the other 2 speakers.

But why?!

The Ric Flair poster is the key to the whole setup.

I plug straight into his WOOOO

A splitter isn't blending necessarily. Do you want to BLEND them and control the amount of blend or do you just want to play two amps at the same time.

Yeah, that's what I spent most of the beginning figuring out.

There's really no way to blend two signals into one cab. Even stereo cabs don't really blend.

He just wanted to know how to set up to play two amps at the same time, I think.

Well if it were a stereo cab, you could use some sort of wah-like footpedal attached to a high-wattage blend pot. I don't know how high pot ratings go but it's something that could be made.

Martin is correct. Blending refers more of a mix thing. All guitar tracks have some mud that does nothing for the tone of the guitar. Getting rid of that mud with EQ or compression. Then I accentuate the exciting frequencies a hair.

I've done blending where I mix a clean tone and a fuzzed out/overdriven together.
My personal favorite is getting two overdriven amps blended. I typically use a bright head and cab with a darker head and cab.

If all you are talking about is running two heads at once, buy an AB switch. buy two rigs and do it.

Probably possible...I've just learned to not mess with anything that might lead to an amp not having the necessary support for the power load...stuff gets bad.

so essentially...I'll leave that to the others.

yeah, he totally wasn't actually asking about blending.

That is true, you would have to put a buffer or transformer on either side of the blend.

You can run an amp at a lower impedance output than the cab. It's actually more efficient. Maximum power is achieved when they're both equal, however.

AB switch it is

It's all about maximum power.
