When a call starts with “We have a dozen color-changing spears that need to be wirelessly controlled”; you know you are having fun. This is exactly the conversation that we had with ShowFX as they prepared for the new Katy Perry tour that launched in Belfast earlier this month. What started with LED spears went on to become mic stands from DAS Design Works, a flying “Prism” and electric guitars from Electrical Guitar Company among other wireless effects.
