with that fx loop box, are you suppose to play a clean channel through it or does it have some fancy switching system for switching out the whole preamp section?
OK - you plug guitar into the E2
You plug the output to the E2 to the return socket on your amp and use the power amp section of your head or combo
This gives you 4 channels of Egnater tone
BUT - you also take two more cables from the back of the E2One goes into the input of your amp and the other goes into the send socket of your FX loop
This allows you to use the channels of your regular amp as well
So via the footswitch you can choose any of your amps regular channels or any of the 4 Egnater channels if you wish
I can see a lot of turing musicians owning an E2 and using uit with any amp they can hire on the road withan FX loop
Then they can always have their own Egnater sounds - plus any that are usable from the hired amp as a bonus
