This is an extension switch designed for use with the LINE6 HX STOMP. It was made because the ones sold by overseas manufacturers were expensive due to exchange rates and shipping costs. ★ "Removable type" extension switches that can be easily detached are also on sale. This is a compact extension switch designed to fit neatly by attaching it to the HX STOMP body with double-sided tape or similar. The total height of the extension switch body is approximately 42mm. It is approximately 38mm when the SW is pressed in. It is recommended for those who are considering replacing their HX STOMP with an XL because the three footswitches on the main unit are not enough. The standard printing is "no printing". If you wish to change it to "45" or "↓↑", please let us know in the comments. The printing is manufactured by changing the material of the housing itself, so it will not peel or disappear. If you wish to have a TRS jack type, please let us know in the comments (+¥500). This cable is not included, so please prepare a 6.3mm standard stereo cable and use it. With the TRS jack type, the extension switch may slightly rub against the Volume knob of the HX STOMP. When attaching it, align it with the lower right position. It will be shipped via Yu-packet Post. The housing is made with a 3D printer, so there may be layer marks, but there is no problem with the strength in use. Please be aware that the housing may deform in environments exceeding approximately 50°C. Since it is relatively weak to force in the lamination direction, please be careful when removing the double-sided tape, etc. We do not provide support for usage, such as setting methods, so please research and use it.
