We need a device to run two heads into one cab

He wants to blend 2 heads to one cab summed to mono. Like a studio blend, but live.


Pretty sure what he wants doesn't exist. Outside of the current multi step solutions used by rack system manufactures...that I have seen. Not an all in one.

Oh.... I misunderstood the question then.

He would need a stereo cabinet then and run one head into one side and then into another but they would not be blendable beside the volume controls on each amp.

The only other way to do it and make them blendable would be to run the amp heads in to loads and then tap the line outs of each amp to a mini mixer of some sort then to a stereo power amp that powers a single stereo 4x12 cabinet.
 
Why are you against stereo cabs? Plug one head into each side, and blend to taste. Seems like a no brainer. What is the exact effect you want that this won't deliver?

To do what you want you need a pair of load boxes, a mixer, and a mono poweramp.

I use both of these and they work great. No tone suck or any issues.These don't " blend" tho.

I have tried blending two heads forever. The way I found to create the blend is to have 2 cabs, two heads and a Lehle ABY pedal. No problems with phase on this pedal. Other specific splitters can stop phase but that was the one I got. The other way to not carry two heads is to have 2 preamps into one stereo power amp then into two cabs. (Or one cabinet with two inputs-ie 2 2x12s in 1 4x12).
 
^^^^ I was just gonna suggest that method too.Ive used the lehle for that also. It works great.
 
Radial Tonebone makes a device to do this
I swear . They had an add for it in guitar world
 
Both amps out to load boxes, out of the boxes to 2 ch inputs on a small mixer. Out of the mixer(mono output) into a splitter, into a stereo power amp, out to 2 cabs...or, no splitter and in to one side of a stereo power amp, or into a mono power amp to 1 cab. Done.
Adjust each ch vol on the mixer to desired mix of each amp, control the overall output with the master on the mixer. You can of course add FX after the mixer and before the power amp, for a WDW rig.
