I've been trying to set up a few of my own patches. When I do this I really just start with an amp and a cab and then start messing with amp settings. I've noticed that when I change to a different amp it then keeps the same settings on the amp from the one I had before. How do I reset that so it's back to default? It appears most of the amp defaults are set up with a low master volume? My patches are for a bedroom so they aren't that loud. Am I best to raise the master to make it louder or just mess with the level? Do most people crank the master or the gain or just stick an overdrive in front of the amp? I've also noticed for example that you can cut of low frequencies in at least 3 different places, does it matter which one you do? Thanks, V15 does sound better to me than V14.
