Hm, I'm not getting this! I'll have a fiddle tonight.
So If I have a factory preset that I really like and then fiddle with it a bit - the B3 automatically saves my tweakings, so I'll have to re-load the preset via a factory reset or using the PC/Mac software?

That does seem to be the case, it's like real pedals there isn't an 'undo' function, I've started saving patches I've made and like on to the computer so if I tweak them but don't like the changes I can get my original back.
