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!
