My new Superdrive 30 112 just arrived today. Couldn't wait to give it a try. Plugged in an, uh, er, the clean channel sounds pretty good, but the drive channel is muddy. And the pull/modern scoop switch doesn't seem to do anything. I'm coming from playing fender and fender-ish amps, so I don't really know what I'm listening to, but the push pull switch not working made me think something might be amiss. I'll listen more carefully again tomorrow. But in the mean time would you say that the effect of the push pull switch could be a subtle thing, or should it be obvious? And would you Budda lovers ever call the drive channel muddy?
