Hi,

1st  -  on half a dozen occasions my code 25 has locked up when saving an edited preset. The only way to sort it is to switch it off and back on again. 

2nd  -  I'm getting a lot of hissing noisy coming through the amp when playing,  when lightly plucking a string the noise is really noticeable this fault is even worse when playing at low volume.

I hope you can offer some sort of fix for these concerns so the experience of play my amp is not a disappointment.

regards.
