This so-called feature is a reason I don't buy amps with shared eq. It doesnt work for me at all. I like to play really clean when I use the clean channel. I tend to use the neck pickup. Dirty I tend to use the bridge pickup. That in combination with the feature of cutting bass for the dirty or lead channel increases the difference to unacceptable levels. I refuse to use an external eq to compensate for what I consider a flaw. An amp like a DSL becomes a one channel amp for me.
