Hi All,
i got a Carmen Ghia head and i am waiting for a new MAZ Jr. head. How can i connect both to my 2x12 cab? I know there is a switch from Tonebone but is quite expensive. Is there any "Y" cable that works in this way in order to use a simple A/B switch to select the head to play? Many thanks to All for any suggestion you can provide.

The reason it's expensive is because if you do things wrong you can blow up your amp. There is no simple Y cord or switch that can do this without significant risk. It's not worth it. If you want to A/B your heads, you need a suitable device to manage the issues at hand.

Steve is 100% correct, you MUST keep a load on the heads at all times, that's what the head bone does.
Do Not use a Y cord, The only simple way would be to run each head to a single speaker in the 2x12 cab by adding an additional jack or two to your cab and use an A/B box to move your guitar signal between amps.

Thanks a lot for you replay. i had the suspect that using a "Y" cable there is too risk and the last thing i want to do is to damage my amp. I will wait to have the possibility to take the Tonebone(have you any others head switch to suggest? i saw somewere that Tonebone have some issues). My cab has already the possibility to works in stereo, so, meanwhile i will use it in this way. Ciao

There are a couple of others, but the only one I can think of just now is made by Axess Electronics. They are all going to have similar constraints because of the nature of what you are doing here. That said, they do work if you pay attention and connect them correctly.

i too was thinking of going 2 heads/1 cab.but i may have changed my mind because of the risk envolved & some of the other things i've heard such as: a slight delay when switching between amps;& you must be careful when using delay pedals{must be run thru effects loop}? might be better off to just carry 2 cabs.

I use the Tonebone to switch heads into one cab and it works great for me. The only "issue," if you want to call it that, is that you can't run time-based effects (delay, etc.) in the effects loop of the amps or you risk damaging the amp if you switch to the other head with the delay still engaged. However, if you run delay in front of the amps then there is no potential problem. Set up like that, I switch back and forth from one head to the other with the delay engaged and it works great--no problem.

deltone is correct - the delay in the loop is the only real issue. In my case I got a bum Headbone I think, but it still works if I'm careful about how I connect it.

Sorry for the stupid question, but why is an issue to have the delay engaged in the loop when switching the head?

Sorry for the stupid question, but why is an issue to have the delay engaged in the loop when switching the head? These devices switch your guitar at the same time as they switch the speakers. You can use a very small resistor as a load if there is no guitar driving the input - that's how they do it. But if you have a delay driving the power amp after you switch, that itty bitty resistor goes "poof".
