Helix LT 4CM , EVH 5150, want to add different pre amps?

[tyz13]

Hi all , I would like to run some different  amps in the 4CM set up, I’m not sure where to place them in the chain. Apparently I can set a switch to bypass my amps pre amp and just use the helix pre amp, but wouldn’t that fit the effects I run to the amps pre?

Any help is appreciated or diagrams, I’m a bit of a newb.

You can place a Helix preamp anywhere in the signal path shown in your diagram and assign a footswitch to bypass it. The key is the bypass state of the  FX Loop. When it is bypassed there is no signal running to/from your physical amp’s preamp section. You will want either your Helix preamp or your physical amp’s preamp active at any time - one of them, not both. So assign the FX Loop bypass to the same footswitch as your Helix amp bypass, and save the preset with one of them active and one of them off. After that, the assigned footswitch will toggle between the preamp sections with one of them always on and the other always off. 

Alternatively, you can create a single preset with multiple Helix preamp blocks (up to the DSP limit) and use snapshots to ensure that only one preamp section (modeled or physical) is active at any time.

 

All of the FX blocks that appear in the signal chain before the Helix preamp and the FX Loop will pass though whichever preamp is active.

Attached is an example of how I do it.

The FX Loop and Helix Amp are next to each other, assigned to FS5, saved with one ON one OFF.

This toggles between the physical amp (Egnater) and the Helix amp.

I use the full amp model, but you can use a preamp model if you prefer.

FX before that are before both amps, FX after are after both amps.

FS11 is a clean boost for leads.
