HX Stomp XL
The HX Stomp's engine — the full Line 6 model library and eight block positions — with eight footswitches, four snapshots, and all of its jacks on one rear panel. It is the version you buy when you want to gig the thing rather than tuck it into a corner of a board.
If yours has three footswitches it is an HX Stomp, which has three snapshots and puts its jacks on three different faces. If it has no amp models at all it is an HX Effects.
Controls and footswitches
Every control on an interactive top panel — eight switches, and the volume knob that presses in.
Inputs and outputs
Every jack on one rear panel, the 3-amp supply trap, and the aux input hiding in the loop.
