Every control on an interactive top panel, including the toe switch and the two EXP LEDs nobody notices.

Every jack on an interactive rear panel — and a straight account of what the LT gives up against the Floor.

The numbers that answer a question, with the Floor comparison on the lines where it differs.

Sound

All 440 amps, cabs and effects decoded from Line 6's own list.

Why it stops you adding a block when the meter looks half empty.

Using it

Pick what you're plugging into and get the cabling and the cab block state.

Which layer a change belongs on, and why the wrong one leaves a gap.

Straight answers to the things people actually ask.
