Cool, you're well on the way now.
if you switch 'off' all the effects, it should be the same as 'bypass', from there setup the input and output levels,
have the output knob at about 12~2 o'clock position, and start with an 'initialised' patch with everything set to 'default' values.
You could check out other premade shared patches and see what settings others use, the factory GT-10B patches are all generally useless,
but learning to create your own patches and dialing in a tone is the way.
Some use the GT in manual mode like a stompbox pedal board, but I find that limiting and better to use patch mode,
I use the 4 patch pedals to have an array of tones from pedal 1 being generic/ordinary to pedal 4 being extreme.
then work your way through the Banks of 4 patches.
