how can I make all my amps work together with one cab? I don't mean a stereo rig, but like having being able to select any amp I want with an A/B/C pedal, like apalmer triline, or something like that.

I'm tired of having to turn on/off, plug/unplug the cap anytime I wanna play all my amps. Sometimes I'm playing my Little Joe, and wanna start playing my Vh4, so I have to unplug, yadda yadda.....

what do I need to get this going?
 
What Terry said - but just two amps.

For three amps I'd get a Tonebone Headbone VT AND and A/B-box (Lehle) AND a loadbox (DIY solutions from Tubetown).
The two Diezels are switched via the headbone into the cab and your little monster is hooked to a load, from its send into a standard A/B (Lehle preferred, cause it handles line signal) and hooked to Einstein's return. A would be Little Joe's send, B would be Einstein's send, Out would be Einstein's return.

Yeah, a lot of cables would be flying around in the back of your amp . . . Its easier to get a couple of smaller cabs actually :D
 
Can someone shed a bit more light on how this actually works? I mean how it is safe that both amps speaker outputs (say 8 Ohm ones) will "see" the constant 8 Ohm load out of a single 8 Ohm cab? I am not sure that I understand how it works (thus it doesn't sound safe to me).
 
The headbone switches two things:

a) the inputs like an A/B box
b) the speaker outs. The unused is going to a more or less fat resistor, which sucks up the wattage - which actually isn't that big, because the input is also set to ground for the unused. Thats why it works flawlessly (I've owned a headbone) - with one exception though: delays in the loop are not allowed anymore, because some wattage is applied "later" to the resistor (because its a delay) and could destroy the resistor and also - caused by that - the OT.
Not a big deal though . . .

here's a clip switching between two Marshalls forth and back which I've made when I had the unit . . .
 
Yes, it does, but a load that doesn't take much wattage. That's why it is important that there is no signal coming through.
 
nice, thanks Olaf....but like you said, too much cables. I might think about the tonebone only for the Einstein/Vh4 or Little Joe/diezel
