Hello, I own an HX effects and I was wondering how to use IR by amplifying it with my Mesa Boogie Dual Rectifier. Would it be safe and work if I : - Plug my guitar into the Mesa - Plug the Send effect loop of the Mesa into the Send of the HX effects - Go through an effect with an IR into the effect loop of the HX effects - Plug the Return effect loop into my sound card and straight into a DAW I know it is required to always have a cabinet plug with the right impedance when using the Mesa, so I would have the master volume pretty low (I have neighbours..). Could it be a problem ? Do I need to plug something into the return of the Mesa ? Thank you!

Hello rd2rk, I tried doing the following, as you said : 1) Plugged a TRS to Tip and Ring to my EXT AMP 1. I plugged the Tip to the Channel 1 and the Ring to Channel 2. 2) I added to my preset : 2 EXT AMP snapshots. The first one is sending a Tip and the other a Ring. 3) When putting on the preset, the amp has 2 channels ON. And the amp buzz... I tried with the Rotary Switch to Footswitch and Channel 2. Any other idea ? Thanks

Hello rd2rk and thanks for your reply! Yes, I configure both PEDAL/EXT AMP output to be EXT AMP command. Note that I tried to set it to pedal, and I didn't see any difference : the channel switch worked fine when no input was plugged. For now, my only need is to be able to switch from channel 1 to channel 2 and the other way around. So far, because channel 2 is the default, if I sent a Tip to Channel 1 it switches to Channel 1 and when I trigger another preset without a TIP signal, it goes back to Channel 2. I bought all the cables of the world, so I am ready to test anything you would find! Thanks

Hello rd2rk, I made more tests yesterday that I will try to explain. First, the Rear Panel CHANNEL SELECT rotary switch is set to FOOTSWITCH. If my guitar is directly plugged into the Mesa input, the HX can switch the channel. I can go from channel 2 to channel 1 without any issue. Once again, I used the Command center -> Instant -> Ext amp 1 -> Tip on a preset. If my guitar is plugged to the HX and my HX to the amp, whenevr I send the instruction to switch the channel, the channel 1 and the channel 2 turn on and the amp start buzzing hard. I tried to plug only the send & return of the HX into my Mesa and I have the exact same problem : both channels turns on. Do you think my HX has a problem ? It's brand new, but it could happen... I could do a video to show you the issue, it clearly doesn't come from the Mesa. The HX react differently when external switching + input are used.

Hello rd2rk, thanks for your reply. Acutally I made a mistake in the terminology, I will try to explain it more clearly : - If the output of the HX is not plugged to the input of the amp, the switching works fine. - If the output of the HX is plugged to the input of the amp, 2 channels turn on instead of switching correctly. The default channel of my Mesa Dual Rectifier is the Channel 2. My Mesa has 5 external switch : Channel 1 , Channel 2, Channel 3 , Solo, Loop Switching to channel 1 works fine with my FXL8 Pro with only one jack from the Trigger to the Amp external switch. To me this is not related to Mesa, because the switching always worked for me on the Mesa. It's only now that I try with a Helix that it doesn't work... Do you see what could cause that, plugging the output of the HX to the standard guitar Input of the Mesa modify the switching behaviour ? Thank you!

Thank you for your replies. Actually the problem comes from the Helix. I have a Harley Benton FXL8 Pro that change the channel of my Mesa perfectly fine by triggering a signal in a standard jack. What is weird is that changing the channel works fine with the HX effects when the input jack is not plugged. As soon as I plug the input, two channels are up together, and the amp buzz. Adding a Voodoo Lab to switch channel in midi is not a good solution for me. I chose HX effects to have a small and efficient solution and because it had an external switch.

I am currently using standard Jack cable (TPI). It was switching my amp channel fine on my previous hardware. I will get a TRS cable and try again. "Mesa Manual states that switching is done by shorting Tip to Ring" : Does this mean that I should send a T + R signal from my HX Ext Amp? My Mesa by default is on ORANGE channel, which is channel 2 for me. Thank you for your help rd2rk, I hope it will end up working, otherwise I would have to get another multi effect pedal :(

Thank you for your reply! I actually still can't make it work. When sending a 'Tip' signal from EXP1 to the external switch 1 of my Mesa, both light from default channel (2) and channel 1 turn on, and it is not how it should be. (Light from channel 1 should replace the light from channel 2...) Do you have an idea of what could cause this issue ?

Hello, I receive my Helix HX yesterday and I can't figure out how to use the Ext Amp function. What I want to do is to trigger the amp channel when selecting a preset. I read all the documentation about v 2.50 (even though i am on the latest 2.82, but the documentation available is not the documentation of the latest version). What I tried is to : - create a new effect by clicking on an empty preset, and then the edit button. - go to the command center - Select the EXP pedal 1 - Press "Save" Before doing that I changed the EXP 1 and EXP 2 to EXT AMP in the Global Settinds -> Preferences. This did not work at all, and I feel that I can not save my command center setting to my effect. I was using a Harley Benton FXL8 Pro to switch my Amp channel until now and it worked fine. I use a Mesa Boogie dual Rectifier. Any help would be appreciated. PS : I tried with the software HX Edit and I couldnt find how to assign an amp switch to an Preset as well. Antoine
