Best way to run two amps at the same time ?

[DannyM]

For now the plan is to run the Twin Jet Uberschall Channel 2 and the 5150 III Stealth Blue Channel simultaneously.

The Lehle Little Dual has a Phase inverter switch so I'm hoping that will help if any phasing issues arise.

Here is the updated diagram:
Guitar > LEHLE Little Dual Amp Switcher >
A: Maxon OD808 > Pro Rack G Ch1 In > Pro Rack G Ch1 Out > EVH 5150 III Stealth > FX Send > Pro Rack G Ch2 In > Pro Rack G Ch2 Out > Nova System Line In > Nova Left Out > FX Return > EVH Stealth 4x12
B: Boss SD-1 > Pro Rack G Ch1 In > Pro Rack G Ch1 Out > Twin Jet > FX Send > Pro Rack G Ch2 In > Pro Rack G Ch2 Out > FX Return > UberCab 4x12

Lehle pedals are pretty good. Stay away from the Morley ABY.

bad experience with the aby also.

agreed on the suckiness of Morley ABY, it seemingly cuts your signal by 50%

This piece is a handy thing to have to kill off any ground issues that often happen with 2 amps:

some would suggest a regular old 2 prong ground lift type adapter on one of the amps when you are running two, in order to break the ground loop.

i would advise against it, as even though you're still grounded through the amp with the ground plug, you're still at risk. you may get shocked. better to not chance it, as there are many devices that have phasing solved, and are cheap enough and not worth risking.

Looks like Disaster Area Designs is about to release a ABY box with midi implementation for changing phase with presets. Check out their facebook.
