Sergio, I have been experimenting with those little switches, and I do not get a decrease in volume at all when going to single coil
I was use to the SE Custom 24 when pulling up the tone control to put it into single coil mode it got quieter, but not with the 408.
Another thing while I am thinking of it, and others have mentioned, the USA posts turn so smooth.
No effort at all, and you really can do it with your pinky
I am sure this guitar is full of many surprises, and I will continue to keep getting impressed with each time I play it.
It is the only guitar I have played since picking it up Friday.
