So im running 2 amps at the same time, My UL half stack , and my Deliverance half stack. When i run both set-ups using a "stereo" pedal to link both heads i get a nasty hum out of 1 side. When i use my Valvulator to run both heads i get no hum...its perfect. So my question is why would i get the hum without using the valvulator, just wondering...obviously im using the valvulator to fix the problem....just wondering why im getting the hum....thanks

Most likely a groundloop that is fixed by the isolated outputs of the valvulator.

You could try to use a signalcable to the humming amp with the shield disconnected on one side.
Or a designated "humcanceller".
Or remove the ground on one of the amps (which is a hazard and at own risk)

Or just use the Valvulator, and gimme the Sig:X because it's feelin' lonely. =D
