Hi to all, i have a ampli tt from 2 days, i have updated the firmware to 2.60 release and i'm not able to save a preset from the app on the amplifi TT. I'm hold and release the tone button for few seconds but nothing is saved on the amplifi tt, simple when i change the bank i lost my preset. It's a bug or i'm wrong something? Thanks in Advance, Fabio From Italy
