It would be great to set a global filter so bass players could HPF the entire out (pre) and out (post) signals. As it stands, the global graphic eq can remove some of the problem frequencies (I'm assuming it's a shelving filter at 30hz), but it'd be much more useful to have a full 4th/8th order sweepable HPF to protect our cabs. As it stands, we have to use an effect block and risk accidentally switching the filter off during performance.
