Hello. I am thinking of trying to run two amps at once. It appears I have a few options:

A splitter pedal- seems to be the best bet but it's the most expensive.

Or using a stereo pedal- I heard the Boss tuner pedal can be used for this but I also
heard it results in tone loss or buzzing or something? I already have a DD3- it has two outputs- would this work?

Or just using a cheap Y-splitter cable- is this sketchy or dangerous?

Note that I'm mostly interested in running both amps constantly for big sound, not so
much on the A/B switching stuff.
Why did you post this twice?

*reported* . I'm guessing since you're a Dec '08er, you probably did this out of ignorance and then posted in the proper forum.
