ohhhh, really, Dunlop?
Yeah, almost a decent pedal... there's just one HUGE problem: it's not switchable between the volume & expression sides. You have to get down on the floor and completely reroute the guitar signal to switch from expression to volume, or invest in an elaborate by-pass AB switching configuration, giving up valuable pedalboard real estate. What Dunlop has done here is the equivalent of designing a really nice car that the driver has to come to a complete stop in order to shift gears in.
Just a little on the extremely dumb side, Dunlop, rendering the Volume (X) extremely worthless.
