It may be a power adapter issue. I had my TF looked at by an electronic wiz and the power adapter was causing the unit to re-boot itself. He fixed the adapter and the TF power connector. I believe this problem caused some of my LEDs to go out on the display, but its still readable.
Luv the Lush sounds, but I've also had to have the foot-switches replaced. (supplied by Eventide). Now the switches are very touchy, but that I can live with! Just a tap on the switch and the TF changes preset.
Ive got mine in the effect-loop with a chorus and a delay unit. Some of the presets are really useless when your giging in a cover-band. But those can be tweaked & saved, or written over by more useable settings.
