Anybody else had this issue?!
I just changed 'MOD' block from a wah to loop mono on a performance slot I was messing around with and it has stuck after a full re-boot even though I hadn't gone through the save process of storing?!
The 'LOCK' button is lit as well as 'ON/OFF' and I don't seem to be able to de-activate either for whatever reason but weirdly pressing + holding 'MOD' doesn't show any padlock symbols associated with the lock feature bit worried and frustrated the slot decided to overwrite itself without my permission!
