LT: expr.2 to switch channels + onboard expr. wah+vol?

[rudomat]

hi,

is it possible on the LT to have the rear expression 2 jack controll my amps channels (via TRS cable) and have the onboard pedal control the wah (pedal1) and volume (pedal2)...?

i try to achieve this...but as soon as i plug the TRS cable into the rear expr.2 jack, the onboard expression pedal won`t change between pedal1 and 2 via the toe switch....isn't that possible...?

thanks!

Global Settings > Preferences > "EXP2/EXT AMP"  (Page 66 in the V3 Manual)

Set that option to "EXT AMP" (external amp)

 

That leaves the built in EXP as 1&2 with the toe switch.

@roryburns...

I think the OP has a Line 6 Helix LT, not a BOSS GT-1.
