I've got a Warwick Streamer with MEC passive pickups, and active electronics. Vol/blend/stacked bass&treble. The pickup is a twin-jazz, so until you move the blend almost all the way, there's not much tone change, as the pickups are right next to each other. I like to change the blend to a 3 way toggle, to make a quicker tone change when needed. Is this possible with the active MEC's? There are small electronic boards on each control. I can post pics if needed. Thanks.
