How does one mix two heads or a head and another power amp and preamp together? Hearing James mixes a VH4 with a mesa power and and triaxis together to get his crunch running into one signal into guitar?
 
James uses a Mesa Boogie High Gain Amp Switcher. These are the best available but out of production. Find one used under $700 on ebay, or on here from time to time. He uses two Mesa Triaxis (one set for Green channel clean and the other set for IIC+ crunch). These are driven by a Mesa power amp. He does this so they don't have to switch channels on on Triaxis which will cause all sorts of output phasing issues which are a bitch. One of these will be blended with his Vh4, which is always on Channel 3. He boosts his leads with a Klon.

Depending on your rig and what you want to do, the best AB/Y pedal for the money is a Lehle. If you don't need to switch, but just blend, the Lehle P-Split is reasonably priced and has ground life/phase reverse. You don't want to go on the cheap here with an amp switcher. I've tried them all and most anything budget priced are POS. You need good isolation here.

Some of the Bradshaw rack gear is good for amp switching, if you can find a used one. The GCX and RJM can work, but you still have to address phase issues and the isolation is not that good on these units without a little help from an additional isolation transformer.

James' Triaxis are also "heavily modified" according ro a "rig rundown" type video I watched on youtube
 
Is the Mesa switcher really that much better than a Radial Big shot ABY or the RJM ABY switcher? They all have the correct phasing capabilities, etc.
 
A lehle little dual will get you there no problem. I use one to switch between my Bogner 20th Shiva and my Bogner Uberschall OR run them together. its a killer pedal. Lehle makes a few different choices for amp switching. This page makes it about as easy as possible to figure out

I have a Radial Bigshot I will sell you! I only used it a few times. Works great.
 
Used the framptone (from robert keeley) A/B box for a few years now. Can either switch between or run both together. Great piece of kit. Never had any issues at all with it.
 
I also have a Radial Bigshot ABY and even though I haven't used it very often, it never seemed to have any issue
I read good things about the Whirlwind selector too, I know Brent Hinds uses one and he's know for using at least 2 amps simualtaneously all the time.
 
It depends on exactly what you have and what you want to do. James uses separate cabs for the power amp and VH4. Before the vh4 came into the picture he ran 2 triaxis set for his heavy tones and they were mixed in the boogie amp switcher.
 
I'm not familiar with how you mix two at the same time. Can you control the mix of each? Or they just both on at the same time? Say I am running a mp-1 via strategy 400 and a c+ at same time and how you blend them? The mesa switcher, I know it will switch between the two of them but will it run them at same time (blend at 50/50) or how does all that work with those lehle dual or radial bigshot pedals? I have a voodoo switcher but assume that does not do this stuff.
 
Sorry, it gets a little confusing with that unit. By "mixing" I actually should have said it will sum your preamp signals. The boogie has isolated transformers and is meant to switch between 4 preamps or heads but you can also combine them.

Say you have 4 preamps. No problem. Plug your guitar into the switcher and then each preamp plugs. To the send and return jacks in the switcher. A single output goes to your power amp. It's controlled via 1/4" cables to turn each loop on or off. To combine them you would just adjust the levels on the preamps. There are no additional controls on the switcher.

To switch preamps and heads, the heads need to either have their own dummy load or cabinet. Then you can turn this on/off and either use the full head with its own cabinet or just the preamp section if it has a dummy load and then summed into the boogie and sent to a power amp and cab.

Lehle kicks ass. S-Go-S is the Benz of splitters.
