Mesa 400 in a dual amp setup, anyone?

[Caca de Kick]

I've been using this lately....
So is anyone else running a Mesa D180/400/400+ in a dual setup with another rig? (one clean, one dirty) If so, are you using the Mesa as a master, then going from slave-out to the 2nd rig. Or are you using some sort of splitter or pedal coming from the bass and going into the inputs of each amp?
I'm trying to find the non-noisy way to run these, as I get a little bit of buzzing sound. It was noisier when I had two Mesa 400's, but is a little less buzzy with my ampeg B15R, or the Carvin amp at the pratice studio.

Yes mate I do this in studio all the time and I have found that a Lehle P Split or Dual is the best for me so far but Little labs and Radial also have good reputations in this field. I have found no luck at all with cheeper designs that don't use a special high impedance transformer.

I use one of these for what you are doing... expensive but its the best solution I have found.

Great! Thanks guys. The P Split II looks like what I'm after.

Okay I sourced the items to do this rig...found a Lehle P Split-II and an old GK400RB both on the ebay. Just waiting for delivery.
