Ok, so I was playing my guitar through my Big Muff Pi, my Small Stone and my Marshall Vibratrem and into the auld Fender Blues Deluxe. The Big Muff was set at the desired volume. When I engaged the Small Stone as well there was a very slight volume boost (hardly noticable), but with the Vibratrem there was quite a noticable boost.
Any ideas why?
I can probably live with it (although it is quite annoying), plus I don't use the Vibratrem that often. It's lack of use is probably why I didn't notice this boost before now...
