Amp Switching A/B Switch Help

[glorioso]

I have read everything but can't seem to find a tutorial that explains how to set up 2 amps in a patch and switch between them. I have even downloaded patches that do this but it doesn't explain how it works. I have made a patch that uses the expression pedal to go from 1-10 on one amp and 10-1 on another, but it always defaults to 1-10 instead of turning off 1 amp and on the other.

 

Anyway, can someone clearly explain how to have 2 amps set up and switch between them? I thought this would be easier like an A/B switch. I will even accept switching between path's but that's not ideal.

 

I know it's probably easy, but I can't figure it out.

 

Thanks for your help

Put in your first amp and assign it to a footswitch.  Put in your second amp and assign it to the same footswitch.  Select one of the amps and press BYPASS to turn it off.  Now one amp will be on and the other off.  The footswitch will now effectively toggle between the two amps.

Thanks! I'll try that.

Now, can you switch between true parallel paths?

Yep, to quote Digital Igloo from the TGP mega-thread:

 

 

 

Inputs and Outputs can't be bypassed in the same way as processing blocks, by design. There are a few ways to do this, however:

• Assign the Output block level to a footswitch (press and hold the Output block's Level knob, press Learn Controller, and press a footswitch)
• Change the Split > Y to Split > A/B and assign the Route To parameter to a footswitch
• Assign a Volume/Pan > Gain block set to –120.0dB to each path, bypass one of them, and assign both to the same footswitch

EDIT: Don't forget to custom label the footswitch! It's easiest to label controller-only switches from the Command Center page. Something like "Swap A-B", "XLRs Off", "DI is My Copilot", that sort of thing.

Here's a little tip for the A/B switch thing... I usually keep a clean(ish) amp and a drity amp within a patch. My A/B footswitch lights up when the dirty (or dirtier) of the two amps is engaged. It helps my brain to distinguish between what's going on since I'm accustomed to seeing an LED light up when I engage an overdrive pedal.

Tonight I used Digital Igloo's path switching advice to create an A/B/C setup with a Randall 1/2 stack, an Alto TS110A and a DT25.  I used 1/4" into the fx return for the Randall, XLR for the PA and L6 Link for the DT.  I was just playing around and wanted to compare the three.  I tried all of his suggestions and settled on using the Split > A/B option.  By the way, the DT25 won easily, clean and with distortion.  

 

The reason there are so many cords is because I was also playing around with 4-cable method into the Randall, an effects loop to try out a couple of pedals and MIDI from my computer to the DT using DT Edit.  Setting up different routing options with Helix is some serious fun.
