Yes to the bright switch, they all have that in common. Not so to the bass boost. Some of them, it seems to be the more directly Marshall like mods, have a mid shift. It's a recessed push button that moves the mid range EQ around a bit. I have that on my SL mod. I think it's only on the "SL" designated mods, including the + and ++ but I could be mistaken on that. It's the only one I've ever seen it on and I've had the Vox, DLX, B'man, EG4, EG3, Plexi and JTM. Can't really remember but I think the Plexi and/or the JTM may have had it. It's been a while.
