Yes, that's all fine but knowing my luck I will reinstall Amblitube and have new problems... I will do that as a last resort. Thanks- just rename the folder where your presets are and to be even safer, make a backup copy of it elsewhere;
- re-install AT5;
- select and cut the default presets folder and paste elsewhere so that it can be useful for future references;
- rename with the right name your old folder;
- then copy Brian and Joe or any other presets from the AT5 backup default folder to your folder.
Much more easier to do than to write
