Is there any difference expected soundwise if I plug my guitar to L/Mono input vs. Right input? My HX Stomp signal chain is mono.   I'm planning to use this right input as a backup in case my wireless unit connected to L/Mono fails. It seems working from my quick test. There was subtle difference but I guess it's buffered (via wireless unit) vs. unbuffered. I want to make sure I'm not doing something st*p*d.
