Hi folks, My Little Lehle is sometimes making an awful popping noise when switching between bypass or loop. I searched the interwebs for a solution, and in the manual (pdf from lehle-site) it is advised to use a dedicated power source for the little lehle. By the way, it only needs power for the LEDs. So my board was powered by a single 1-spot with a daisy chain, wich could be the cause. I decided to try it at home, with a seperate 1-spot for the lehle, wich seemed to solve the problem. Now here's my question: I'm considering buying a T-rex fuel tank Junior (It is supposed to have isolated outlets, and I only have 9V pedals), but would the result be the same? Or do I need a really dedicated power source for the Lehle? Thanks for your interest!
