Thank you both.
I got another TRS to double TS insert cable, and replaced the first cable with the newer one. Still got the same problem. Then I found this Reddit post:
I made a minor change to my Global Settings:
Global Settings
EXP/FS Tip: EXP 1
EXP/FS Ring: FS8
FS7 Function: All Bypass
FS8 Function: Toggle EX
I made sure the insert cable was connected between SP1-L6H and HX Stomp XL as follows:
Tip (Black) is plugged into OUT 1
Ring (Red) is plugged into OUT 2
The TRS end is plugged into the Line 6 (EXP 1/2 - FS7/8)
FX:Pedalbored preset settings:
Wah - Bypass - Footswitch 8
Wah - Position - EXP Pedal 1
Volume - Bypass - Footswitch 8
Volume - Position - EXP Pedal 2
Couple of things that I did not know/get that were tripping me up:
- Wah and Volume should not both be set to EXP Pedal 1. One needs to be set to 1, the other to 2
- Really need to put your weight into the toe switch. Light tap on the switch is not enough pressure to switch pedal function.
