A piece of shrink tubing with adhesive approx. 6 … 7 cm long, for electrical insulation of Imps and Goblins.
If the socket/switch assembly (Imp) is not possible or the assembly with the goblin screw set is not possible, the shrink tube is another method to safely house the electronics in the effects device. The shrink tube is heated and fits securely and tightly around the Imp/Goblin. It can then no longer cause a short circuit in the effects device.
This piece is enough for one Goblin, or two Imps.
