Hi, it's me responding to my own post - not sure if this is considered gauche.
What I discovered is this:
- when plugging the G10 transmitter into the guitar it establishes connectivity with the receiver at 1/8 volume on the guitar - very low volume.
- when attempting to wake-up from sleep mode the volume level on the guitar must be set to at least 50% if not higher - much higher volume.
- if one selects high E the volume must be higher compared to low E.
- I play at lower volumes because I'm very close to my amp.
- when I use headphones (wireless) the volume from the headphones can be adjusted so this can mask/hide the difference between initial and wake-up volume requirements.
- to compensate for this inconsistency when playing without my studio headphones I turn up the volume on the guitar and lower the input on the amp.
- I like the Relay G10 but this to me is a design inconsistency.
Now that the nature of the unit is more apparent I can deal with this. They've should consider resolving the USB design - not good.
